Winchester 1866 Prototype Musket

Today, were taking a look at a Winchester prototype developed in the mid-1860s, a period when Winchester was seeking to build on the success of the 1860 Henry Rifle and place the company on a firm financial footing. Oliver Winchester had taken control of the New Haven Arms company before the Civil War and while for a time it had been known as the Henry Repeating Arms Company he eventually sought to put his stamp on the company, renaming it Winchester Arms Company in 1866. At the same time he decided to focus the company’s energies on winning military contracts around the world.

This developmental prototype is in the ‘musket’ configuration: with a longer barrel, a bayonet lug and a wooden forend. The prototype represents one of the many developmental steps towards what would become the Model 1866. It has a number of interesting features – a steel, rather than brass, receiver and a hinged loading port developed by Nelson King, Winchester’s superintendent between 1866 and 1875.

The rifle itself was built by Luke Wheelock, Winchester’s model room mechanic and a designer in his own right who would go onto develop his own rifle designs for Winchester.

King’s 1866 patent (US Patent Office)

The rifle is 54.5 inches long, with a 33.75 inch barrel. Believed to have been built in 1866, it is chambered for a .45 calibre rimfire round. King patented his loading port in May 1866. He described how the port worked:

“Through one of the plates S (preferring that one upon the right-hand side) I form an opening, 0, as denoted by broken lines, Fig. 1, and also seen in section, Fig. 7. This opening is formed so as to communicate through the frame directly to the chamber E in the carrier block, as seen in Fig. 3. Through this opening, and while the carrier-block is down and all parts of the arm in a state of rest, insert the cartridges, point first, through the said opening in the plate S into the chamber E the second cartridge pressing the first into the magazine, and so on with each successive cartridge until the magazine is filled, or until the requisite number has been inserted therein, the follower G being pressed up before the entering cartridges. In the rear of the chamber E2 the frame forms a shoulder to prevent the cartridges from being forced out through the opening in the plate S3 is a cover for closing the opening in the plate S3 and is hinged thereto, as seen in Figs. 1 and 7, the hinge being provided with a spring,a1, the tendency of which is to open the cover C. A spring-catch, d, (see Fig. 1,) secures the cover when closed, so that by pressing upon the said catch the cover will fly open. After the requisite number of cartridges have been placed within the magazine, close the cover, as seen in Figs. 1 and 2.”

To paraphrase: ammunition can be loaded through the opening in one of the receiver side plate when the carrier block is down, insert the cartridges through the opening, pressing the first into the magazine and so on until the magazine is filled… a cover for closing the opening is hinged to the receiver side plate. A spring catch secures the cover when closed.

According to Herbert Houze, King developed the covered loading port design in early January 1866, with a design drawing dating to the 14th January, confirming this.

King altered the design of the rifle’s cartridge carrier so that a cartridge could pass through its lower section straight into the magazine when the action was closed. In theory the aperture could be placed on either side of the receiver, in practice is was placed on the right. Prior to this Winchester had experimented with systems where the tube could slide forward (G.W. Briggs US #58937), a port in the base of the receiver (J.D. Smith US #52934) or a sliding forearm covering a loading port at the rear of the magazine tube (O.F. Winchester UK #3284 [19/12/1865]).

DSC_0686

King’s system had the benefit of allowing the rifle to be quickly loaded or topped off without rendering the rifle unusable while loading. Positioning the port in the receiver allowed the magazine tube to be enclosed by a wooden forend.

A cartridge guide was fitted inside the receiver which guided rounds through the cartridge carrier and into the tube magazine. The rounds were prevented from popping out of the magazine, when the carrier was aligned and the cover open, by a shallow shoulder which projected in line with the carrier’s channel to hold cartridges in the tube by their rim.

DSC_0685

The hinged cover is held shut by a spring catch mounted on the rear of the cover. When the knurled section on its front is pressed rearwards the cover pops open. The spring catch is actuated when it tensions against the cover’s hinge as it is closed. On the back of the cover there is also a cartridge stop for when the cover is closed.

Another small but interesting feature of the prototype is the catch at the rear of the lever loop, this differs from the manually turned catch seen on the Henry and production 1866. This design appears to be a much better safety feature, simply requiring the user’s hand to depress the catch to unlock it from the stock. It also appears to be a much simpler mechanism than that seen in later models like the Model 1895. The trigger also had an extension protruding from its rear which appears to prevent the trigger from being pulled when the lever isn’t full closed. Neither of these features appear in King’s May 1866 patent.

It appears that the idea of the port with a hinged cover was superseded by what we now recognise as the classic Winchester loading gate in the summer of 1866. King’s new system replaced the hinged cover with a piece of stamped spring steel attached to the inside of the receiver side plate by a screw. The spring steel gate could be pushed in, with the nose of a cartridge, to allow rapid loading. The front face of the gate formed a cartridge guide removing the need for the separate machined guide used in King’s earlier iteration of the system.

King’s revised loading port system required just five, rather than twelve, components: King’s altered cartridge carrier, receiver side plate, spring metal loading gate plate and retaining screws. This simple but elegant design continued to be used for decades on various models of rifle. The company were so pleased with the refinement of the rifle that, according to R.L. Wilson, King was awarded a payment of a $5,000 reward by the company’s board of directors.

Winchester introduced the rifle in 1866, with the first deliveries being made early in 1867, the new rifle was offered in various barrel lengths and patterns including carbine, rifle and ‘musket’. Winchester found some success selling 1866 rifles to the militaries of France and the Ottoman Empire, while many other countries purchased rifles for testing including Britain and Switzerland (whom came close to adopting the Winchester.) The rifles also found success on the civilian market with around 4,500 sold in the first five months.

The Scientific American described the new rifles as “elegant in appearance, compact, strong, and of excellent workmanship. On examination we find its working parts very simple, and not apparently liable to derangement.”

King incrementally developed his loading system before radically simplifying it and this prototype rifle represents an important developmental step in the design of what would become the Model 1866 – one of Winchester’s most important rifles.

SOE Sabotage – Plastic Explosive

During the Second World War Britain’s Special Operations Executive (SOE) developed a whole series of sabotage devices for use behind enemy lines. Using unique archival footage this series of short videos examines some of the weapons developed for use by SOE agents in occupied Europe. In this episode we look at the component which made so many of them possible – Plastic Explosive. This video contains demonstrations of various uses for the malleable explosive.

The footage, believed to have been filmed in 1940, is part of the Imperial War Museum’s collection, it shows plastic explosive being demonstrated in a number of different applications. It was filmed by Cecil Vandepeer Clarke, a British engineer and sabotage expert who was a member of the Special Operations Executive and worked at a number of weapon research and development centres during the war.

Plastic explosive and its effect (IWM)

The clip features a number of men preparing and shaping plastic explosive charges, adding fuses and detonators.  The explosive is then seen being applied to a steel plate in a ring shape, before being detonated. The resulting explosion punches a round hole through the plate. The film also includes demonstrations of what plastic explosive pressed against a tree trunk can do. Once detonated the roughly 1 foot thick trunk is splintered in two. Metal girders are also shown being prepared with a substantial block of explosive being pressed into its seams.

The SOE’s 1944 Descriptive Catalogue of Special Devices and Supplies lists the ‘Standard Charges’ of 1.5lbs or 3lbs of plastic explosive with an integrated central primer available in rectangular blocks inside a rubberised fabric. Of course SOE agents were taught to use as much or as little explosive as was needed for the task and they were taught to be able to improvise in any given situation.

Given the date of the footage the explosive being used is likely and early form of plastic explosive produced at Woolwich arsenal, possibly PETN or Cyclonite better known as RDX, which would have been mixed with a plasticiser to make the explosive malleable.

SOE Sabotage – Magnetic Petrol Tank Bomb

During the Second World War Britain’s Special Operations Executive (SOE) developed a whole series of sabotage devices for use behind enemy lines. Using unique archival footage this series of short videos examines some of the weapons developed for use by SOE agents in occupied Europe. In this episode we look at an explosive magnet bomb, designed to be attached to any magnetic surface and detonate to destroy machinery or vehicles. It later evolved into the small pocket-sized ‘Clam mine’.

Today, we’re lucky enough to have some colour footage showing the of testing of a magnetic bomb which could be attached to the petrol tank of vehicles. The footage comes courtesy of the Imperial War Museum.

New Movie (2).Movie_Snapshot
A still from the footage showing the charge placed on the body of the car (Imperial War Museum)

From the film we can see that the bomb consisted of a small block of plastic explosive, a pair of strip magnets (or possible a horseshoe-shaped magnet) and a Switch No.10 time pencil delay detonator. The explosive block itself looks to be slightly smaller than the SOE’s standard 1.5lb charge.

In the film we see the bomb placed on the boot (or trunk) of a saloon car before various civilians and a corporal experiment with various ways of covertly attaching the bomb to the underside of the car. At one point the corporal allows himself to be dragged along behind the vehicle before making his escape.

Luckily the 16mm footage, filmed by Major Cecil Clarke, also shows us the effect of the explosive charge mounted on a petrol tank full of fuel. According to the details listed for the film by the Imperial War Museum the footage was filmed in 1940, at SOE Station XVII, located at Brickendonbury House in Hertfordshire.

New Movie (3).Movie_Snapshot
A still from the footage showing the bomb’s magnets (Imperial War Museum)

This configuration of the bomb doesn’t appear in the Special Operations Executive’s Descriptive Catalogue of Special Devices and Supplies published in 1944. However, Colonel Leslie Wood, Station XII’s commanding officer, described the demonstration put on during a visit by Brigadier Robert Laycock of the Commandos and William Donovan, the head of the American OSS in June 1942. One of the scheduled demonstrations was the “Effect of small ‘magnet’ charge of explosive on petrol tank of car.”

It appears that this ad hoc magnet charge evolved into ‘the Clam’, which was a smaller, version of the magnetic Limpet mine. The Clam evolved through a number of marks with the MkI having a stamped sheet metal casing and the later MkIII using a bakelite, plastic casing.  Both were made up of a plastic explosive charge inside a rectangular, rounded case with a pair of magnets at either end. They were detonated by either a Time Pencil or an L Delay fuse attached to a No.27 detonator. The MkIII had 8oz (226g) of high explosive filler, such as TNT/Tetryl 55/45.

While unlike the larger Limpet they weren’t developed for under water use but the Clam could be mount onto any vaguely flat magnetic surface including engine blocks, fuel tanks, crank cases, cylinder blocks, rail tracks and steel plate.

At just 5.75” x 2.75” x 1.5” they were easily concealable, could be carried in a pocket and were non-descript enough not to draw attention. An estimated 68,000 Clams were made under supervision at Aston House according to Des Turner’s book on Station XII.

Madsen M50 – Live Fire

The M50 is one of the quintessential early Cold War submachine guns. Cheap, simple and utilitarian. It evolved from the earlier M46 and was developed by Dansk Industri Syndikat in Denmark. The M50 has a simple blowback action, is chambered in 9×19mm and feeds from 32-round double stack single feed magazines.

The weapon’s has a clam-shell like receiver that hinges at the rear and allows the barrel, bolt and recoil spring to be removed. The M50’s folding stock has a leather cover and while the length of pull is a little short it provides a decent cheek weld.

New Movie (2).Movie_Snapshot
Madsen M50 (Matthew Moss)

The M50 has a relatively slow rate of fire of around 500 rounds per minute which makes it very easy to make single shots while in full-auto. The sights are extremely simple with a single rear peep sight.

It has manual safety switch on the left side of the receiver which locks the sear in place and a spring-loaded grip safety just behind the magazine well. The amount of pressure needed to disengage it is minimal and a firm firing grip of the magazine is all that is needed.

The Madsen went through a number of changes with various models having different magazine release types, selectors and manual safety positions. The M53 introduced in 1953, fed from a curved magazine and had an improved magazine release. Some models had an additional fire-selector and the safety moved back above the trigger. Some models retained the forward grip safety while others moved it to behind the pistol grip. Some patterns of M53 also had a barrel shroud for mounting a bayonet as well as added wooden panels on the pistol grip.

SOE Sabotage – The Incendiary Case

Following on from our last video & article looking at Explosive Coal, we continue our series looking at some of the sabotage weapons developed by Britain’s SOE during the Second World War.

We’re lucky enough to have some unique colour footage showing the of testing of some of these explosive devices and in this article we will examine an incendiary-filed case.
In this piece of 16mm colour footage, filmed in 1940 by Captain Cecil V. Clarke, we see what appears to be an attaché case containing three medium-sized bottles, which likely contains a mix of petrol and paraffin or some white phosphorus, prepared for testing at the bomb range at Brickendonbury in Hertfordshire, a Special Operations Executive training and research centre codenamed Station XVII. It’s believed that these films may have been produced as teaching aids for the agents trained at Station XVII and this film may have been shown during a lecture.

New Movie (2).Movie_Snapshot.jpg

While incendiary briefcases, attaché cases and even suitcases are listed in the 1944 SOE Descriptive Catalogue of Special Devices and Supplies they were quite different from this case. They were primarily designed for the quick destruction of documents and items carried inside them. They used sheets of potassium nitrate to burn the case’s contents.
The incendiary case seen in this footage on the other hand appears to be designed to be clandestinely placed and detonated with a delay fuse, to set nearby flammable objects on fire. What was described as a ‘Delayed Action Incendiary’.

IMG_20200625_124643.jpg
The Incendiary Suitcase entry from the SOE’s Descriptive Catalogue of Special Devices and Supplies

In this footage of another separate test we get an idea of the destructive capability of just one of the bottles.

It’s possible that this incendiary case was a proof of concept test for the later cases or perhaps a demonstration of a concealed incendiary device Station XVII were working on. SOE developed a large number of bespoke explosive devices for various missions, so while this device may not have become ‘standard issue’, it may have been developed for a specific purpose.

SOE Sabotage – Explosive Coal

During the Second World War Britain’s Special Operations Executive (SOE) developed a whole series of sabotage devices for use behind enemy lines. Using unique archival footage this series of short videos examines some of the weapons developed for use by SOE agents in occupied Europe. We begin the series with a look at the history and development of Explosive Coal. Explosive coal was designed to explode inside fireboxes, furnaces and coal stores hampering enemy infrastructure.

545343
A still from the film showing a close up of the Explosive Coal (IWM)

I came across this footage while doing some research in the Imperial War Museum’s online catalogue. This piece of 16mm film was filmed by Cecil Vandepeer Clarke, a British engineer and sabotage expert who was a member of the Special Operations Executive and worked at a number of weapon research and development centres including MD1 at Whitchurch and SOE Station XII at Aston.

SOE or Special Operations Executive were a clandestine force tasked with conducting irregular warfare behind enemy lines including sabotage, assassination, intelligence gathering an small scale raiding. One of the sabotage methods developed was introducing an explosive charge into the boiler firebox of a ship or a locomotive or a power station or factory’s furnace. This achieved by disguising the explosive as either a piece of fuel like coal or wood or even as a dead rat – which might be tossed into a firebox or furnace to be disposed of.

CoalTorpedo
What is believed to be one of Courtenay’s ‘Coal Torpedos’

The idea of ‘Explosive Coal’ wasn’t new. The idea originated from the US Civil War, when Confederate Captain Thomas Edgeworth Courtenay designed a piece of cast iron, with a cavity which could be packed with gun powder, that looked like a lump of coal. The Courtenay described them as ‘Coal Torpedoes’, their aim was to damage a steam ship’s boiler enough to cause a catastrophic secondary explosion. While several vessels may have been damaged or sunk by these Coal Torpedoes, the claims are difficult to confirm.

It seems the idea of a coal bomb was resurrected in 1940 and initially a ‘Coal Borer’ was developed and available for use in theatre by mid-1940. The borer could be used by agents to make holes in lumps of coal which could be filled by plastic explosive and a detonator. This was soon superseded by an Explosive Coal Kit which included moulded fake coal and paints to allow agents to match the colour of local coal. The kit included instructions on how to prepare and use the coal bomb.

Arthur Christie, a lab assistant at Station XII, is quoted at length in Des Turner’s book on Station XII. Christie remembered being asked to drill large holes in some coal:

“Another task was collecting the biggest lumps of coal that I could find in the storeroom and taking them to the lab. I had no idea what they wanted them for; it was seldom explained to me and, when it was, it was often as clear as mud. My instructions were to try to drill a large hole in each piece of coal without shattering it. I tried with a brace and a six-inch long tube that had a serrated end. I found that, if too much pressure was applied, the coal would disintegrate. I thought, I wonder what the hell they want this for? Don’t ask, just do it, and I did manage to drill three lumps of coal. I placed the drilled coal on the table of the MI room and set off for the officers’ dining room to inform the CO that I had been successful. I was told to insert about a quarter of a pound of PE and a detonator into the hole and glue the coal dust back over it. The mud in my brain now began to clear. The lump of coal could be placed in the coal tender of a locomotive and find its way into the firebox, or perhaps into the furnace of a factory. Later the PE was dyed black, which was better than using coal dust and glue. This idea led to plastic explosive being moulded into a multitude of objects and colours to fool the enemy.”

Frederic Boyce & David Everett, in their book SOE: The Scientific Secrets, credit Station XV with the development of a moulded clam-shell design using dyed Herculite plaster and coated with real coal dust. A photograph of this can be seen in the SOE’s Descriptive Catalogue of Special Devices and Supplies, along with ‘Explosive Wood’, or as it was officially known ‘Wooden Logs, Explosive’.

Coal
Entries for Explosive Coal and Explosive Wood from a reprint of the SOE’s Descriptive Catalogue

Eventually this was replaced by a bomb based around a charge in a metal casing that allowed liquid plaster to be poured around it, simplifying production and removing any sign of a seam. The coal bombs were detonated by a No.27 Detonator to which either a match headed safety fuse or a time delay fuse was attached.

Once the danger of coal bombs was discovered by the enemy it was also believed that they would have considerable a psychological impact and also cause the enemy to expend considerable resources on protecting and checking coal supplies.

The ‘Explosive Coal’ we see in the footage appears to actually be an incendiary bomb, producing a large amount of flame and heat. This would have been ineffective in a boiler but with a time delay or other sort of fuse it may have been very effective in causing a coal bunker fire aboard a ship, in a factory store, at a coal depot or in a locomotive’s coal tender. Coal fires are extremely difficult to contain and put out.

How effective Explosive Coal was is unclear but it is believed that coal bombs were used by both the SOE and their American counterparts the OSS. Boyce & Everett estimate that about 3.5 tons of explosive coal was made between 1941 and 1945. I’m unsure how many of these were explosive and how many were incendiary, like that seen in the footage here,  but it’s a fascinating asymmetric method of targeting enemy infrastructure at the most basic level.

Diemaco/Colt Canada M203A1

The Diemaco M203A1 is a development of the M203 40x46mm low velocity grenade launcher. The M203 was initially developed by AAI to replace the Colt XM148 which proved overly complex when tested in Vietnam.

The Diemaco M203A1 improves on the earlier launcher by incorporating its sight into the mount rather than being atached to the top of the barrel. The Diemaco M203A1 should not be confused with the Colt-manufactured M203A1 in US service. The Diemaco launcher is offered alongside the C7 and C8 rifles made by Diemaco (now Colt Canada).

Diemaco developed the M203A1 so it has a longer action, with the breech opening further to allow the firing of all 40×46 mm LV grenades including less than lethal baton rounds. It can also be mounted on all AR-patterned rifles as well as the Steyr AUG.

Like the original M203 the launcher can be operated by either a left or right handed users. The original model had an iron sight assembly has dual azimuth adjustment knobs and an elevation dial, this model, however, has a simplified tangent sight. Diemaco stated that the M203A1 has a maximum effective range of 400m (440 yd) with a muzzle velocity of 78 m/s (260 ft/s).

The M203A1 was tested by the UK’s special forces in the late 1990s, when they evaluated the Diemaco SFW carbine, which was subsequently adopted as the L119A1. The Heckler & Koch M320 GLM (HK AG36) has since been adopted by the British Army.

US Tanks of WW1

The US entered the Great War with no tanks of their own – by the end of the war they had designed and built their first tank, collaborated on a leviathan heavy tank with Britain and built their own copy of the French FT. In this video we look at how the US Army hit the ground running and formed two tank corps and built their first tanks.

In recent videos we’ve looked at all of the US Army’s early tanks, here’s a round up:

Ford M1918 3-Ton Tank

165-WW-313A-020 - Copy

The tinny 3-ton Ford was the first American designed and built tank. Aiming to use readily available parts and materials it took inspiration from the French Renault FT but was smaller and lacked the FT’s revolutionary turret. The Ford was only lightly armoured and did have the best cross country handling. Check out our full article on the Ford here.

MkVIII ‘International’ Heavy Tank

111-SC-68498 - Copy

The MkVIII was a truly ‘international’ effort with the US, UK and France all working on the project. The US and UK provided the mechanical components while France provided a factory to assemble the formidable vehicles. The MkVIII wasn’t ready in time to see action during the war but remained in US service into the 1930s. Check out our full article on the MkVIII here.

The M1917 Light Tank

111-SC-53605 - Copy

The US also sought to produce their own licensed version of the French Renault FT, making some slight changes the tank was adopted as the M1917 but despite production being well underway by late 1918, none of the M1917s reached the front. Instead they became the backbone of the US Army’s interwar tank force. One even climbed a mountain!  Check out our full article on the M1917 here.

Remington’s Hybrid .303 M1903

In 1940, following the evacuation from Dunkirk the British Army was in desperate need of small arms, with over 100,000 rifles left behind in France. In dire need of rifles Britain turned to the US and its huge industrial base and approached a number of companies about tooling up to produce Lee-Enfield Rifle No.4s. Savage Arms took on one contract and projected production of 1,000 per day but establishing production of a rifle US companies didn’t have the tooling and gauges for would take time.

remington_1903_303_rightwm
Right side of the Remington (Matthew Moss)

Remington was also approached by the British Purchasing Commission and asked if they could manufacture up to 400,000 rifles. Remington estimated it would take up to 30 months to tool up for No.4 production. However, Remington believed that if they could lease the old tooling previously used at the Rock Island Arsenal to produce M1903s, from the US Government, they could tool up to produce the M1903 in just 12 months. It was suggested that the tooling be adapted to produce rifles chambered in the British .303 cartridge. Some ergonomic changes could also be made so the rifles mimicked the British No.4.

On 12th December 1940, the British government issued a Letter of Intent to Remington for the manufacture of 500,000 rifles in .303 British. Some sources suggest the British agreed to an advanced payment of $4,000,000. Much of this covered the lease, transport and refurbishment of the M1903 tooling. The rest went on the purchase of raw materials and the necessary accessories for half a million rifles.

The tooling lease was agreed in March 1941, and the US Government also supplied 600,000 stock blanks which had been in storage in exchange for ammunition produced by Remington. With the passage of the Lend-Lease act, on 11th March, the Remington contract came under the control of the US Government, rather than a private order. Remington received the last tooling shipments from Rock Island Arsenal on 22nd April, and by the end of May had the production line up and running.

A contract to produce the hybrid rifles at a cost of $5 per rifle was agreed in late June. Remington’s engineers began setting up the equipment and working out an ad hoc production layout that would allow 1,000+ rifles per day to be built. At least four pilot models were built, with some of these guns being sent to Britain. The rifles were reportedly received in September 1941, and following preliminary examination were described as “very successful”. Four of the rifles were distributed for further testing but by the end of 1941 the project had been abandoned.

Remington made a number of external and internal changes to approximate the British No.4. They fitted a front sight post with sight protectors which was moved further back from the muzzle to enable the rifle to mount a Rifle No.4 spike bayonet. As such the upper barrel band does not have a bayonet lug.

Many of these parts are still in-the-white, unfinished, including the barrel, barrel bands, floor plate, front sight assembly, rear sight assembly and the bolt itself. The bolt does, however, have a parkerized cocking piece.

The hybrid also moves the rear sight back onto the receiver, which necessitates a longer piece of wooden furniture covering where the M1903’s ladder sight would normally be. The style of rear sight was also changed to a two-position flip sight with apertures for 300 and 600 yards mimicking those seen on the No.4 Mk2.

They also redesigned the charger guide to support the Lee-Enfield-type chargers rather than the M1903 stripper clips. The bolt was adapted to work with Britain’s rimmed .303 round, with the extractor modified for the British cartridges wider, thicker rim.

The rifle did not have the Lee-Enfield’s detatchable box-magazine, instead retaining the M1903’s 5-round internal magazine. The magazine follower does not appear to have been altered either. Markings on the rifle are minimal and include a ‘7’ on the front sight post, a ‘B2’ on the bolt handle and a ‘2’ stamped on the magazine follower. No roll marks or serial numbers appear to be present.

The rifle’s stock has also been adapted, so instead of a straight wristed-stock a piece of wood has been spliced in to create a Lee-Enfield style contour, forming a semi-pistol grip. The stock is marked with the inspector marks ‘WJS’, which indicate the stock was originally inspected by W.J. Strong and accepted between 1918 and 1921, as well as a pair of later Springfield Armory inspection cartouches: ‘SPG’ – the initials of Stanley P. Gibbs, who was an inspector at Springfield Armory between 1936-1942 and ‘GHS’ – the initials of Brigadier General Gilbert H. Stewart (GHS), Springfield’s commander in the late 1930s- early 1940s. This would suggest that the stock was refurbished at Springfield Armory before being transferred to Remington where it was subsequently adapted.

In August 1941, the US began its re-armament programme and in September the British contract with Remington was cancelled. At the same time production in Canada and at Savage’s J. Stevens Arms division in the US had gotten underway and it was decided that the adapted hybrid .303 M1903s developed at Remington was no longer needed. The hybrid contract was formally cancelled in December 1941, and additional .30-06 M1903s and M1917s were taken under the Lend-Lease Agreement to fulfil the needs of the Home Guard. Savage believed that they could significantly increase the number of rifles they could build per day, they managed to enter full production by the end of 1941 and by 1944 had produced well over 1 million No.4s.

1903A3

Remington went on to produce M1903s for the US military, overcoming issues with the original engineering drawings and the tooling dimensions to eventual produce 365,000 M1903s by mid-1943, before switching to production of the M1903A3 pattern and producing 707,629 rifles. In total Remington produced 1,084,079 M1903-pattern rifles during World War Two.

The Remington .303 M1903 hybrids are perhaps the rarest M1903 variant, with only a handful built. They would likely have been perfectly serviceable rifles and helped plug the desperate gap in Britain’s arsenal. Rapidly moving events ensured that these rifles became a footnote in both the Lee-Enfield and Springfield 1903’s histories.

Special thanks to both Remington and the Cody Firearms Museum for allowing us to take a look at this extremely rare rifle.

The Sten Gun, Its Name and the Men Behind It

The Sten is one of Britain’s iconic Second World War Small arms. Two men are principally responsible for its development Colonel Reginal Vernon Shepherd and Mr. Harold John Turpin a pair of small arms and engineering experts with considerable experience.

Turpin was born in Kent in 1893, served his apprenticeship as a draughtsman in Erith and in 1922, he joined the drawing office at the Royal Small Arms Factory Enfield – Britain’s principal state small arms centre.

Reginald Shepherd was born in 1892, received an Bachelor of Science Degree from Leeds University in 1912. In October 1914, he joined the West Yorkshire Regiment as a second lieutenant, serving in Gallipoli and Egypt. After the war, with his engineering background, he assigned as 2nd Assistant Superintendent at the Design Department at RSAF Enfield in December 1922, and promoted to captain.

The two men found themselves joining Enfield at around the same time. In November 1933, Shepherd, now a major, was appointed Inspector of Small-Arms (Class 2) at Enfield and assisted in getting the Bren light machine gun into service. He remained at Enfield until 1936, when he retired from the army and spent a short spell at BSA before being recalled. In late 1939, Major Shepherd returned to active service and once again took up the position of Inspector of Armaments, this time at the Ministry of Supply Design Department at Woolwich Arsenal.

By the outbreak of the Second World War Turpin had become the senior draughtsman at Enfield and when the development of the Lanchester Machine Carbine began he was paired with Major Shepherd to draw up technical drawings for the gun’s production.

The two men decided that a simpler, cheaper submachine gun could be produced and in December 1940 set about designing it, with Turpin in the lead. During the Winter of 1940-41 the first prototypes were built. Development of the first Sten – the T40, was completed on 8th January 1941, taking just 36 days.

14 pilot models were ordered but only two were completed by engineers at the Philco Radio Works in Middlesex: T-40/1 and T-40/2. The gun was initially designated the ‘T-40’ or Turpin, 1940. By the end of January 1941, it had become known as the ‘ST Machine Carbine’. The ‘Carbine, Machine, STEN, MkI’ was approved for issue on 7th March, 1941, with 100,000 guns ordered.

How did the gun become known as the ‘STEN’ and what did Sten stand for?

We know that the ‘S’ stands for Shepherd and the ‘T’ for Turpin, but what about the ‘EN’ – it is generally accepted to represent ‘Enfield’. Why? Because RSAF Enfield is synonymous with British military firearms. Additionally the Bren light machine gun’s name is a portmanteau of ‘BR’ from Brno, the location of the Czech factory the zb.26/30 originated from, and ‘EN’ for Enfield, the British factory that anglicised the design for British manufacture and service.

Enfield, however, wasn’t where the Sten was designed. Turpin and Shepherd claimed that most of the work on the design had been done out of hours. Additionally, during the winter of 1940, the Armament Design Department was relocated, from Enfield to a former Drill Hall in Cheshunt, Hertfordshire to escape the bombing of London.

While the Sten may not have been designed at Enfield, the first prototype was partially assembled there with work also done at Turpin’s own home workshop. A further 46 pre-production pilot models were later ordered from RSAF Enfield, in February 1941.

Intriguingly, early accounts suggest that ‘EN’ may have stood for ‘England’ – not ‘Enfield’. In October 1942, the fifth instalment of ‘Know Your Weapons’, a semi-official series of weapons manuals printed by the publisher Nicholson & Watson, explains that ‘EN’ did in fact stand for ‘England’.

In June 1943, Turpin penned a semi-anonymous article for ‘The Model Engineer’, about the design and development of the gun, which repeated this claim. An October 1943, article in the US Popular Mechanics magazine, entitled ‘Machine Guns from Backyard’, includes a supposed quote from the inventors explaining that the “E and N stood for England.”

A more official account came in June 1949, at a hearing of the Board of the Royal Commission Awards to Inventors (a board set up to reward inventors who had done important war work). One of the board members Lord Justice Sir Lionel Cohen asked Shepherd: “Why was it called the Sten?” The colonel replied: “It was called the Sten by the then Director General of Artillery. The ‘S’ was from my name, the ‘T’ from Mr. Turpin, who was my draughtsman and who did a very large amount of the design, and the ‘EN’ was for England. That is the origin of the name, for which I accept no responsibility.” This suggests that the ‘EN’ standing for ‘England’ may have originated from the upper echelons.

Sadly, there was no officially published explanation of the name as official manuals rarely go into superfluous detail. In 1948, however, Ian Hay published R.O.F. The story of the Royal Ordnance Factories, 1939-1948 in which he stated the ‘EN’ was a reference to the Enfield factory. Similarly, another early published account, D.M. Ward’s 1946 The Other Battle, a history of BSA, also suggested it represented the factory name.

In truth it is difficult to know exactly what the ‘EN’ stood for. It may be that both Enfield and England were discussed and used by various individuals and offices. There may have been an element of propaganda to including ‘England’ in a weapon’s name which led senior officers to push this in the press and direct the gun’s inventors to suggest this was the case too. Of course the authors of those earlier books may have mistakenly believed ‘EN’ stood for Enfield, as it does in Bren. Personally, I’m inclined to follow the primary sources attributed to the two men responsible for the design, and believe it initially stood for England.

Shepherd was awarded an OBE in January 1942, and became the Assistant Chief Engineer Armament Design (A/CEAD), he was promoted to Lt. Colonel in August 1943. He retired from active duty at the age of 55, in January 1947, and was removed from the reserve list. He was granted the honourary rank of colonel. He died in April 1950, aged 58. Turpin retired from RSAF Enfield in 1953, and died in April 1967, aged 74.

Beyond a pair of discretionary payments, £1,500 to Shepherd and a small payment of £200 to Turpin, neither man was officially rewarded as they were deemed to have essentially done what they were paid for, designing small arms. Scant reward and recognition for a weapon which became one of the key wartime small arms of the British and Commonwealth forces.

Our thanks also to Jonathan Ferguson, of the Royal Armouries, for sharing his thoughts on the ‘Enfield’ vs ‘England’ debate.
