Northern Ireland Sterling Clone

From the late 1960s into the 1990s, Northern Ireland suffered a long period of sectarian violence, commonly known as The Troubles. Without going into too much detail about the conflict, other sources do a much better job than I can today, the violence saw Irish Republican paramilitary groups, Ulster Loyalist paramilitary groups and British security forces involved in a protracted low-level conflict with a Republican insurgency fighting not just British forces but Loyalist paramilitaries like the Ulster Volunteer Force (UVF), the Ulster Protestant Volunteers (UPV) and the Ulster Defence Association (UDA). This article/video has no intention to comment on the conflict itself, merely examine a weapon produced during the period.

This copy or clone of a Sterling Mk4 / L2A3 submachine gun is believed to have been assembled by Loyalist paramilitaries although which group and its origins are unclear. Loyalist groups during the 60s and 70s tended to be less well armed and relied more heavily on improvised small arms and weapons stolen from military and police armouries and personnel than Republican groups. When tensions rose in the late 1960s, the Loyalists were largely equipped with obsolete and outdated weapons.

Sammy Duddy, a member of an early Loyalist group, the Westland Defence Association, and later a press officer for the Ulster Defence Association, recalled the dire state of their arsenal at that time:

“[…] we had no guns. The IRA had automatics [machine-guns], high-velocity sniper rifles, powerful pistols, the lot, but we had fuck all. There were virtually no guns on the Loyalist side. The only weapons we had were baseball bats and I just thought to myself, ‘what the fuck are we going to do when they [the IRA] come in with their machine-guns? Throw bats at them?’”

The Ulster Volunteer Force (or UVF) took to stealing what weapons and spare parts they could from the British military and Royal Ulster Constabulary. Weapons assembled from damaged captured Sterlings and Sterling spare parts kits became common. In this case, this weapon has a number of cannibalised original Sterling parts which have been paired with a craft-made receiver tube. From examination we can see that the weapon’s end cap has a Sterling part number stamp ‘CR110’ inside. Similarly the weapon has a factory-made plastic grip. Other factory made parts include the helically grooved bolt, the two recoil springs and the charging handle. There is also seemingly a factory-made trigger group and magazine release button. The magazine is well sized and utilises various parts from a Sterling’s magazine release including the button, an set screw and catch piece.

The weapon uses a Sterling’s factory-made pistol grip and trigger mechanism – a remarkably sophisticated craft-made weapon (Matthew Moss)

The trigger assembly housing is welded and ground smooth where it joins with the tube receiver. On factory-made guns there is a visible seam. The poorer quality tube steel of the receiver also appears to have drooped or bent a little around the middle of the weapon. The holes in the barrel shroud are of uniform size but they are roughly drilled and not equally spaced. At the front of the receiver we can see they have retained the barrel with a pair of large bolts, suggesting that the barrel may have been factory made too. There is now end cap catch at the rear nor provision for a folding stock either. While whoever made the receiver tube went to the trouble of added hand stops found on the actual Sterling they are clearly only lightly welded on.

Another difference is the absence of a bayonet lug on the left side of the barrel shroud, and a much cruder fixed sight sat within a U-shaped piece of metal welded to the tube receiver – to act as a front sight protector. The factory-made Sterling’s front sight is adjustable and the sight protectors are folded forward and aligned across the tube receiver. The rear sight and its protectors appears to have sheared off at some point. The only marking on the weapon, ‘29992’, is crudely electro pencilled on the top of the magazine housing, where you’d normally see markings saying ‘Sterling Mk4’ or ‘L2A3’. When that crude serial number was added is unclear. The black paint on the receiver is wearing thin and we can clearly see some file marks in places.

Hundreds of craft-made submachine guns were built to feed from Sterling and Sten magazines and there are numerous surviving examples of guns made from box tubing – often parts were clandestinely made in Northern Ireland’s factories and at shipyards like Harland & Wolf in Belfast – giving rise to the name ‘shipyard special’. Other nicknames included ‘rattlers’ and table leg guns.

The origins and story behind this particular weapon remain unknown, it is today part of a UK Ministry of Defence collection and said to have been found in Northern Ireland during the Troubles. Regardless it’s a very interesting piece of clandestine engineering which shows considerable skill in its assembly. Which is unsurprising as there are numerous accounts of skilled machinists working on illegal firearms parts during the period.

Old Gun Ads: How Did Colt Advertise Its Guns?

In this video we’re taking a look at something very rare, a pre-1911 catalogue produced by Colt. But it isn’t a catalogue to order guns from. Instead, it’s a catalogue to order gun advertisements from! Old firearms ad from this period are fascinating and give us an insight into who markets company’s were aiming their products at.

The catalogue includes illustrations of pistols and entire print ads which could be printed locally. It covers most of the commercial Colt line ranging from Colt Model 1908 Vest Pocket pistols, to Colt Police Positive revolvers and Colt’s military automatic pistols.

New fangled Colt automatics (Matthew Moss)

The catalogue’s introduction explains Colt’s advertising strategy, saying:

“we advertise in the big national mediums to CREATE A DEMAND ON YOU for our arms; these advertisements are read by thousands of perspective customers IN YOUR LOCALITY, therefore YOU can obtain the benefit of SALE by local advertising.” It’s a sound enough strategy.

My favourite ad, featuring Browning’s Colt M1895 machine gun (Matthew Moss)

Only one ad includes a Colt product that isn’t a pistol. The ad above features an illustration which includes John Browning’s first machine gun, the Colt-produced Model 1895. It’s an evocative advert including revolvers, a semi-automatic pistol and the 1895.

Colt Model 1907 Military pistols, the predecessor of the 1911 (Matthew Moss)

One of my favourite parts of the catalogue covers Colt’s burgeoning automatic pistol line. This section actually helps us date the catalogue as there are no 1911s. It includes the Colt 1907 Military, the Colt 1902 Military, the Colt 1903 Pocket Hammer and the Colt 1903/1908 Pocket Hammerless automatic pistols.

Some of the illustrations of Colt’s revolvers available for printing (Matthew Moss)

The catalogue includes printable illustrations of the Colt ‘New Service’, the Colt ‘Army Special’, the Officers Model Target, the Police Positive Special, Police Positive and Police Positive Target. As well as some classics, with a full page of Colt Single Action Army revolvers.

Some cutaway diagrams of the Colt Pocket Hammerless (Matthew Moss)

WW2 Makeshift Sten Foregrips

A couple of weeks ago we looked at some photographs showing an interesting modification seen on a STEN MkII held by Deputy Prime Minister Clement Attlee. The STEN Attlee posed with had a front grip added, something the MkII didn’t typically come with.

A few people very kindly sent me some other contemporary photos showing other ad hoc STEN front grips so I thought a follow up video was needed. I also found a group of photographs taken in June 1943 at the Combined Training Centre at Kabrit, in Egypt. The photos show groups of Commandos and the Royal Navy’s Naval Beach Parties armed with Stens with a pretty standardised style of front grip.

Commandos on parade with STEN MkIIs equipped with ad-hoc front grip, at Kabrit in June 1943 (IWM A17755)

In these photos we can see the men training with the STENs and the front grips are quite clear. It’s especially interesting in that it isn’t just the Commandos who have the front grips but also men of the Naval Shore Parties. It’s also relatively rare to see STENs in North Africa. You might have seen some of these photos, taken by Royal Navy photographer Lieutenant L.C. Priest, in our video looking at the unusual fighting knives the Commandos are equipped with.

The plethora of photos from Kabrit show a fairly standardised design for the grip. A metal ring, seemingly tightened by a wingnut on the left side and a generous wooden grip that was long enough to fit all four fingers on. The grip appears to have some finger grooves and a fairly standard shape. A photo (see above) of Naval Commandos on parade shows the men with the STENs tucked under their arms, holding the front grips. This is identical to how the STEN MkI with its front grip was paraded with. The photo also gives us a good look at the uniformity of the grips.

RAF Regiment Corporal cleans his STEN MkII, equipped with a makeshift front grip (IWM CM4296)

While the photos from the Combined Training Centre at Kabrit represent the largest number STEN front grips seen in one place and several units there are a few other photos which are really interesting. First up is this photograph of a Corporal from the RAF Regiment taken in Libya sometime in 1943. The Regiment had been formed just a year earlier. The corporal is sat cleaning his STEN MkII with the butt removed but the bolt still in the weapon. On the barrel nut of his weapon he has a wooden front grip. Again seemingly attached to a metal band around the barrel nut. The wooden grip appears to have some rudimentary finger grooves. Sadly, I couldn’t find any other photos of this Corporal and his STEN. But the design of his front grip is very similar to those seen in the Kabrit training photos and could well be of the same origin.

Finally, we have a photograph from a completely different theatre – Burma. The caption for this photograph reads: “Men of the 2nd York and Lancaster Regiment searching the ruins of a railway station for Japanese snipers, during the advance of 14th Army to Rangoon along the railway corridor, 13 April 1945.” This soldier’s STEN MkII has a grip just in front of the trigger mechanism cover and behind the magazine housing and ejection port. It’s actually in a position close to that of the original STEN MkI’s integral folding pistol grip.

Soldier of the 2nd York and Lancaster Regiment with a STEN MkII outfitted with a homemade front grip, Burma 1945 (IWM SE3804)

At the end of the day the adaptation is a good idea, a front grip provides a means of pulling the weapon into the shoulder and a more natural place to grasp other than the barrel nut, the trigger mechanism housing or the magazine – which was discouraged. It is interesting to note that I’ve yet to see any examples of a MkIII being fitted with a front grip like these.

This is certainly something I’m going to do more research into to see if there’s any documentary reference to the use of front grips like these. With the introduction of the MkV, with its front grip, it seems that the idea was sound enough. If you know of any other examples let me know in the comments!

John Browning’s 1895 Slide-Action Prototype

By 1895 Winchester had been considering a slide-action rifle for some time, in 1882 William Mason had begun work on one (US Patent #278987) to counter Colt’s slide-action Lightning only to drop it. Finally in 1890, Winchester introduced a slide-action .22 calibre rifle developed by John Browning. The Model 1890 became extremely popular.

Between 1887 and 1895 Browning patented four slide-action rifle designs. The first of these, US patent #367336, was granted in July 1887, this was followed in 1888 by US patent #385238. In September 1890, the Browning brothers were granted US patent #436965, which along with the previous 1888 patent protected what became the Model 1890. Three years later Winchester introduced the Model 1893 pump action shotgun, that would eventually evolve into the famous Winchester Model 1897.

Right-side close up of the rifle with its action open (Matthew Moss)

Finally, April 1895, Browning filed a patent for a design for a .30 calibre rifle which was granted in September 1895 (US patent #545672) This patent covers the rifle we’re examining here. The rifle itself is a slide or pump action in long barrelled configuration which Winchester described as a ‘Musket’.

The September 1895 slide-action design was purchased by Winchester but like so many other Browning designs, it never entered production and Winchester purchased the design purely to secure it and prevent other rival manufacturers picking it up. Winchester instead went with a lever-action design, patented in November 1895 (US #549345), which became the famous Winchester Model 1895.

A left-side view of the rifle’s receiver with Browning’s patent overlaid (Matthew Moss)

The September 1895 slide or pump-action rifle design had a laterally camming locking breechblock. As we can see, externally Browning’s toolroom prototype looks somewhat similar to the contemporary Winchester Model 1895, with a single-stack integrated box magazine but with a pump sleeve rather than a lever. 

An action-bar connects the slide/pump to the front of the breechblock/bolt carrieron the right-hand side of the rifle. The slide handle itself is made of a U-shaped piece of metal which wraps around the rifle’s forend. The slide has been roughly cross hatched to improve grip. There is a channel cut into the furniture for the action arm’s attachment point to travel. The slide is attached to the arm by a pair of screws.

A close up of the rifle’s slide/pump handle (Matthew Moss)

However, Browning developed this prototype to allow loading of the magazine from below rather than through the top of the receiver. He added a hinged floor plate, with a spring loaded follower, that allowed loose rounds to be dropped into the magazine and then closed.

As we open the magazine, hinging the cover plate down, we see the carrier flip down against the plate to allow loading. The rifle was designed to be loaded from below with the bolt forward.

Browning’s September 1895 patent (US Patent Office)

In the patent description Browning explained that his aim was to improve breech-loading box-magazine firearms by designing:  

“…a simple, compact, strong, highly effective, and safe gun, containing comparatively few parts and constructed with particular reference to provision for charging the box-magazine with cartridges from the bottom of the frame of the arm while the breech-bolt is in its closed position, so that the arm may be charged without operating its action mechanism or disturbing the cartridge in the gun-barrel, if one is there.”

Browning’s September 1895 patent (US Patent Office)

From the original patent drawings we can see the flat spring which acted on the carrier running below the barrel, ahead of the magazine. Inside the magazine are a pair of what Browning refers to as ‘spring fingers’ these act on the cartridges inside the magazine and keep them properly aligned, seen here in Fig.7 of the patent. In Fig.8 we can see what Browning calls a ‘box-like guideway’ which guide the rims of the cartridges, “preventing the cartridges from being displaced while being fed upwards.”

The rifle’s breechblock locked into a recess in the left side of the receiver, tilting at an angle with the rear of the breechblock canting to the left. When the pump handle was pulled rearwards the breechblock cammed laterally to unlock the action, extracted and ejected any spent casing and when the slide/pump was returned forward a new cartridge was picked up from the magazine, chambered the breechblock locked again ready to fire. The rifle’s hammer was cocked by the rearward movement of the breechblock.

A left-side view of the rifle with its action open, note the complex machining on the rear of the breech bolt (Matthew Moss)

Externally, the slide-action’s receiver looks similar to that of the production Model 1895 but internally they are very different. The action is certainly less open than the Model 1895’s but the lateral locking mechanism is less robust. Additionally, with no lever, as in the Model 1895, the slide-action rifle lacks the safety mechanism which prevents the action from opening accidentally.

A view inside the open magazine with the floorplate hinged open (Matthew Moss)

The model is in the white and while externally the machining and tool work is very neat, inside the action we can see where the cuts in the receiver wall have been more crudely made. In terms of design, the slide-action prototype was certainly simpler and had fewer working parts than the Model 1895 lever-action.

Winchester purchased the .30 calibre slide-action design but never produced it, it is believed that only Browning’s prototype was built to prove the concept. The prototype was part of Winchester’s collection and may now be found at the Cody Firearms Museum.

Screw-Breech Percussion Rifle Prototype

In this video and article we’ll examine a somewhat mysterious screw breech percussion rifle – if you, like me ever wondered what a Ferguson with a percussion lock might look like then you’ll find this one fascinating. If you haven’t seen our earlier video on Patrick Ferguson’s 18th century breechloading rifle, check that out!

Right profile of the rifle (Matthew Moss)

This rifle likely dates to the mid-1860s and from some research is believed to be based on a design patented by Lewis Wells Broadwell, an American inventor. Broadwell was granted his first patent in 1861, protecting a sliding breech design for artillery. During the 1860s & 70s Broadwell was employed as the European Sales Agent for the Gatling Gun Company. He held a number of firearms and ordnance related patents, granted between 1861 and 1876. With several relating to artillery carriages, ammunition and magazine systems. His screw breech (US #33876) and a gas check (US #167981) designs for artillery were used by Krupp in some of their guns including the popular 68mm breechloading Mountain Gun.

The rifle with its trigger guard rotated forward and its breech open (Matthew Moss)

Like the earlier Ferguson rifle, which drew heavily on earlier screw breech designs, this rifle has a rotating trigger guard which acts as a lever to unscrew the breech. Rotating the trigger guard drops a rectangular breechblock and opens the action. Unlike the Ferguson the threaded piece does not act as the breech plug itself, instead the separate breech block takes the brunt of the cartridge ignition.

The rifle with its breech open (Matthew Moss)

Broadwell filed the patent believed to correspond to this rifle first in Britain, in May 1863, and subsequently in the US in August 1865 (US #49583). The patent protected the breech action and depicts what Broadwell described as a ‘screwed nut’ below a rectangular vertically sliding breech block. This idea of a sliding breech-block builds on his earlier patent for a sliding cannon breech.

Broadwell’s UK patent, dated 1863 (UK Patent courtesy of Research Press)

In Britain, Broadwell used Richard Brooman, of Robertson, Brooman and Company, as a patent agent. At the time Brooman’s company offered a service by which he acted as the inventor’s deputy and was listed as the patent holder, while the inventor was listed as the ‘communicator’. The service cost the not insignificant sum of £45 (at the time a labourer could earn just 3 shillings 9 pence per week – or 15% of £1 – that’s just under a year’s average wages). This initial sum covered the patent for three years. It is likely Broadwell employed an agent because at the time he was living in St Petersburg in Russia, undertaking negotiations with the Russian Government to establish Gatling Gun production. Brooman was also the editor of The Mechanics’ Magazine, a Victorian science and industry journal.

Broadwell’s slightly different 1865 US patent which is also similar to the rifle we are examining (US Patent Office)

The breech plug has a screw thread with a very wide pitch with flat crests. Broadwell’s US patent describes the breech plug as having a ‘three to six threaded screw’. The breech blog falls enough to allow loading after turning the lever around 200-degrees – ensuring a rapid action. Interestingly the British patent shows the lever not attached to the base of the screw plug but instead shows it at the mid-point of the screw. This may be an error in the drawing. It seems that if the rifle we are examining is a Broadwell prototype it was decided to simplify the action by attaching the lever at the base of the plug.

A close up of the rifle’s trigger guard and screw (Matthew Moss)

This rifle itself, has no markings whatsoever, not even range markings on the rear sight. Typically rifles of this period would at least have a marker’s or patent holder’s mark on the barrel or lock plate. This suggests that the rifle is either unfinished or more likely a prototype which did not require extensive markings.

The rifle’s unmarked rear sight (Matthew Moss)

The breechblock is not blued and is possibly case hardened. Much like the Ferguson, and other earlier screw-breech rifles the trigger guard also acts as the breech lever. Which with a rotation of approximately 200 degrees, descends enough to open the breech and allow access to the chamber. The threaded screw is around 0.5 in (1.2cm) thick and acts on a rectangular breechblock which sits above it. This basic layout matches Broadwell’s 1863 UK patent.

The rifle with its breech partially closes, there is no method of extraction indicating it used a combustible cartridge (Matthew Moss)

The rectangular shape of the breechblock ensures a strong action as it butts up against a pair of narrow shoulders (about 1mm in width) at the rear of the receiver. The rifle has a two band stock and a cleaning/ramrod which indicates a military-style rifle but interestingly, there is no obvious provision for fixing a bayonet.

The rifle is believed to be chambered in a cartridge using a .451 Westley Richards projectile. There is no method for extraction so we can safely assume the rifle used a combustible cartridge, ignited by a percussion cap rather than a self-contained metallic cartridge. Interestingly, the UK patent also suggests the use of a “tubular magazine… formed in the hammer, containing self-acting feeding apparatus for supplying ignition wafers or patches to the nipple.” This is not mentioned in the later US patent and the rifle we’re examining has a conventional capped percussion lock.

A close up of the Note rectangular breech with the action closed (Matthew Moss)

The US patent describes a ‘mechanism to prevent the gun from being fired when the breech is open’, this is formed by a lever which disengages with the trigger when the breech lever is rotated. There is a small leather flange in the base of the stock where the screw ascends and descends, this prevents the ingress of dirt and also acts to keep the screw clean.

Left profile of the rifle (Matthew Moss)

Compared to Patrick Ferguson’s action Broadwell’s design simplifies the breech plug using a simpler to manufacture rectangular breechblock and a thinner screw plug. The use of a self-contained cartridge would have sped up loading but the need to cap the rifle’s nipple was still a limiting factor. The screw breech concept became increasingly obsolete with the introduction of self-contained metallic cartridges with integral primers as well as the introduction of faster actions including bolt actions, falling block actions and toggle-locked lever actions.

Lewis Broadwell was born in Cincinnati, Ohio, on 18th July 1820. He is perhaps best known for his drum magazine design for the Gatling Gun. The Broadwell Drum consisted of a series of single stack, gravity assisted magazine columns arrayed around a central pivot point. These columns held between 15 and 20 rounds depending on calibre and typically there were 16 columns of ammunition. Broadwell patented the drum’s design in December 1870. It was used extensively during the 1870s by a number of militaries around the world, including by the British Army. Broadwell was granted his last patent in 1876 and died, aged 86, in May 1906.

Special thanks to the Hayes collection for letting us take a look at this very interesting rifle. Thanks to David over at the Research Press for help finding the patent and to John Walter for his help finding information on Broadwell himself.

STEN Magazine Loaders

While the ongoing Coronavirus pandemic has prevented some archival research I had planned which would have informed much of the STEN series, our good friend Richard at the Vickers Machine Gun Collection and Research Association, has come to our aid and we’re able to cover some of the loading accessories developed for the Sten’s magazines.

As we know the Sten uses a 32-round double stack, single feed magazine which can trace its origins back through the Lanchester Machine Carbine to the Haenel MP28,II’s magazine designed by Hugo Schmeisser [patented in 1931].

Sten Magazine, inert 9x19mm rounds and MkII and MkIV magazine fillers

The nature of the single feed makes the magazine difficult to load by hand with the last few rounds very hard to insert. So a series of four marks of ‘magazine fillers’ were developed. These are described in the British Army’s official List of Changes in February 1943.

The MkI is described as consisting of “a lever mounted on a short case which conforms to the shape of the magazine. It is hand operated, the loading lever being given a rocking motion during filling. The MKI slipped over the top of a magazine with a rivetted spring tab which indexed into a notch in the front of the Sten mag.

A cutaway showing the MkII filler

The MkII is very similar but simplified by having the spring catch mounted on the rear instead of the side and engaged a “small rectangular slot on the magazine”. The rear of the spring is turned up slightly to allow the user to remove its from the magazine.

The MkIII, which is possibly the rarest of the fillers, is described as:

“hand operated but of different design from the MkI and MkII. It consists essentially of a spring loaded vertical plunger which is attached externally to a case, the latter to assemble on the magazine. There is no retaining catch. It comprises the following parts:

Case. Is a rectangular shaped steel pressing with a tube of rectangular section welded thereto. The latter, which houses the plunger and spring, has a hole trilled at the lower end to accommodate a pin which restricts the amount of movement of the plunger and acts as a stop for the compressing spring.

Plunger, loading. Is made of two laminated steel strips welded together the top part of which is set to form a handle. The body of the plunger is slotted to accommodate the compression spring. The top part is splayed to form a suitable contact with the cartridge.”

List of Changes, Feb. 1943
Sten accessories including a sling and a MkII magazine filler

The other more common filler is the MkIV. Which is a much simpler design with a loading lever mounted on top of a clip which is attached to the rear of the magazine body and retained by a spring similar to that of the MkII.

Rich has very kindly demonstrated the use of the two most common fillers – the MkII and the simpler MkIV. It takes Rich just under 2 minutes to load that magazine, but he was doing his best to show various angles and unlike a British soldier during the war he hasn’t regularly loaded magazines with one of these fillers either. Despite that the clip gives a good idea of how fast you could load a mag once you’re in the groove.

With the MkIV filler Rich was able to load the mag in about 1 minute 15 seconds, the stability of resting the base of the mag on the table helped with the MkIV’s simpler design.

Manual diagram showing both the MkII and MkVI

Also, as a follow on to our previous episode looking at the Sterling Submachine Gun’s magazine Rich has also demonstrated the loading of a Sterling mag to its 34 round capacity. No magazine filler needed with George Patchett’s double-stack, double feed magazine.

Steyr AUG with HBAR Barrel

Sometimes all is not as it seems. That was the case when we examined this Steyr AUG. From the barrel and bipod it appeared to be an AUG in an HBAR or Heavy Barrel configuration but on closer inspection we found that it was in fact a rifle receiver, bolt and bolt assembly and chassis that had been paired with an HBAR barrel assembly.

Ordinarily, the HBAR could be modified to fire from an open, rather than closed, bolt. This example has the standard AUG progressive trigger for semi and full-auto. It does not have the modified bolt carrier, striker or trigger mechanism.

The HBAR has a 4x optic, rather than the rifle’s 1x, while the HBAR-T can be fitted with an optic like a Kahles ZF69 6×42.

Adoption of the AUG HBAR does not appear to have been widespread and Steyr don’t currently list it as an option amongst their upgraded AUGs. For more Steyr we have previously examined a Steyr AUG SMG conversion and a Steyr MPi 81. We’ll take an in depth look at the AUG and AUG HBAR in the future.

Specifications (for a standard AUG HBAR):

Overall Length: 35.5in (90cm)
Barrel Length: 24.4in (62cm)
Weight: 8.6lb (3.9kg)
Action: Gas operated, rotating bolt – the HBAR typically fires from an open bolt, but this rifle-based example fires from a closed bolt.
Capacity: 30 or 42-round box magazines
Calibre: 5.56×45mm

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.

Left & right profiles of King’s prototype musket (Matthew Moss)

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.

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]).

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.

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.

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.

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.
