Suppressed Sten Mk4

The MkIV is the missing link between the most utilitarian Sten, the MkIII, and the final iteration – the wooden-stocked MkV. Very little is known about the MkIVs development and more archival research is needed.

The weapon was on display at the Morphy Auctions booth. While they couldn’t disclose which collection it was on consignment from, they noted it was believe to have been brought home by what they described as ‘a US Commando’. Not the clearest provenance but more might be explained in the auction catalogue when it publishes in a couple of months’ time.

There are several variants of the MkIV – what have become known as the MkIVA and MkIVB. This weapon is one of three examples of suppressed MkIVAs, the others are in the Royal Armouries’ collection.

The Royal Armouries also has unsuppressed examples of the MkIVA and MkIVB. This is an unsuppressed MkIVA. I couldn’t find any decent resolution photographs of the MkIVB but as you can see it has its pistol grip and trigger assembly moved forward significantly.

The gun appears to have been using a Sten MkII receiver and its magazine housing is marked as such. Interestingly, it doesn’t have a MkII serial number, instead it is marked ‘3’. This is similar to one of the MkIV’s held by the Royal Armouries. On the underside of the magazine housing is a further serial number ‘R83297’. Morphy’s noted that they believed the gun, or the MkII receiver used to make it, was produced by BSA.

The trigger mechanism has been moved forward about 1 inch (2.5cm) and unlike any other Sten is enclosed by a large bow trigger guard, suitable for cold weather use with gloves. The unsuppressed MkIVA has a 3.5 inch barrel tipped with a conical flash hider, however, this example is suppressed with what Peter Laidler, in his Sten book, mentions is an MG-D 3748 silencer designed by the Armament Design Department. 

One of the most interesting differences is the shorter cocking handle slot in the receiver and the different design of cocking handle. This gun’s cocking handle is designed to be rotated 90 degrees to lock the bolt in the forward position. This is a departure from the earlier locking method of pushing the cocking handle down to lock into a hole in the other side of the receiver.

The other most distinguishable feature is the folding stock. This design is shared by the A and B variants and is made of a tick steel bar which pivots. The pivot point is in line with the front of the pistol grip. To deploy or fold the stock a small spring-loaded catch is pull towards the butt, this allows the stock to be pivoted through 180-degrees to the left. While the catch locks positively, if the small coil spring which provides tension was damaged the stock would unlock making it difficult to use. The coil spring is also exposed which could allow it to snag on things or become clogged with mud.

But who was the MkIV designed for? According to FWA Hobart’s book on submachine guns the MkIV was developed for airborne troops – a prior to this paratroops had dropped with the stock removed from their Stens. Hobart suggests that the MkIV guns were abandoned because they didn’t fare well in trials due to a high, uncontrollable rate of fire. Whatever the reason they never entered service and only a handful of prototypes were made.

Thank you to Morphy Auctions for letting me take a look at the MkIV – its set to be on sale at their upcoming Firearms Auction in April. 

One thing I’m looking forward to doing this year is doing some archival work, digging into the surviving records regarding the Sten and hopefully uncovering more on the MkIV.

Update – 01/03/23: Morphy’s auction listing for the weapon has been published and offers some detail on the Sten’s origins and some excellent photographs. Below is an extract detailing the Sten’s provenance:

“This particular specimen was issued to an American officer who was training in England and was intended to be landed in Japan as part of pre-invasion operations in 1945. According to the officer at the time of the gun’s purchase, when the invasion was called off the authorities never asked for the gun’s return. The officer brought the gun back to the United States and subsequently registered it with the BATF.”

Second World War Anglo-American Ammunition Contract

Recently a very interesting document surfaced in an online auction, while it eventually sold for more than I could afford, I thought it was worth sharing some of the interesting images of the document that were shared in the auction.

Front page of a draft contract for ammunition, drawn up between the British Purchasing Commission and the Western Cartridge Co. (via War-Office)

The document is a draft of a contract to order .303 ammunition from the Western Cartridge Company, part of the Olin Corporation. Before the US passed the Lend-Lease Act, in March 1941, which cleared the was for greater material assistance from the US to Britain the British Purchasing Commission was tasked with procuring arms, ammunition and materials from US companies.

First page of the contract (via War-Office)

The document, originally drawn up in December 1940 called for a mind-blowing 75 million cartridge per month. To do this the Western Cartridge Company needed to expand its production capacity. The contract deals with the intricacies of expanding the company’s manufacturing base and how this expansion would be paid for.

A still from a British newsreel c.1942, showing a British ammunition factory.

The contract states that the .303 ammunition would be for aircraft, for use in weapons like the belt-fed .303 Browning machine guns used in the RAF’s bombers and fighters. The contract mentions that a total of 750 million rounds are required. 20% of these could be requested, at a month’s notice, to be tracer rounds.

It is fascinating to see not only the typed and stapled amendments but also the handwritten notes in the contract’s margins which change quantities, dates and other details. The ammunition is described in ‘Exhibit F’ of the contract as being ‘MkVII .303’. The contract also mentions that the Western Cartridge Company could use its own smokeless powder for the first 100 million rounds and subsequently either their own or powder from Du Pont or the Hercules Powder Company. This means that the ammunition was probably MkVIIIz, as the cartridges did not use Cordite. It is unclear whether the projectiles to be used in the Western Cartridge Co. cartridges used the MkVIIIz boat tail .303 projectile.

A still from a British newsreel c.1942, showing .303 ammunition being tested at a British ammunition factory. The ammunition is being tested in a Vickers Gun, a Bren LMG, a Vickers K and a .303 aircraft Browning

The Western Cartridge Company was not the only US ammunition manufacturer to produce .303. Winchester, another Olin Corporation manufacturer, and the Peter’s Cartridge Company also produced .303 MkVIIIZ.

Sadly we don’t have the rest of the document to examine but these pages offer a really interesting insight into how Britain was procuring ammunition for various weapons during the early part of the war when the situation looked increasingly desperate.

Pages from the March 1941 contract (via War-Office)

A subsequent auction listing for ‘Contract No. A-1562. Requisition No. U.S.233. Dated March, 1941’ also calls for a substantial amount of ammunition, some 400,000,000 rounds. The 42 page contract refers to the ammunition as MkVII and notes the use of Hercules Hivel 300 powder and describes it as ‘S.A. Ball .303 with American modifications dated 7 November, 1940’. The March 1941 contract also states that depending on testing it could be used for ground or air use.

Talking PIATs with Military History Visualised

Had the absolute pleasure of chatting about PIATs with Military History Visualized.

Ever since I wrote my book about the PIAT I have been passionate about explaining why it was actually a pretty decent bit of kit, just much maligned.

Always great to Bring Up The PIAT! Do check it out below:

A Look Inside A Heavily Damaged M3 Grant

I recently attended the We Have Ways of Making You Talk podcast’s history festival and one of the most striking things on display was a very rusty, heavily damaged M3 Grant! 

The tank, T24193, was one of the first M3 Grants to arrive in Britain in 1941. It was used for cross country and gunnery trials before later in the war it was used as a range target. The owner was kind enough to share some photographs of the tank before it was salvaged.

The tank was salvaged from Pirbright Ranges in Surrey in 2003 and restored mechanically but its external damage is going to be retained as a visual display of its history as a range target. According to the tank’s owner the M3 was used to test captured German Panzerfaust and Panzershreks and has approximately 100 10mm diameter holes from Panzershreks and nearly 400 12-13mm diameter wholes from Panzerfausts fired at the tank. There also appears to be larger holes, perhaps some HESH round damage and lots of small arms strikes or spalling marks.

Here are some photos of the tank:

I would love to read the report on that testing to see what they were trying to find out – a possible research project for the future. The Panzerfaust (capable of penetrating up to 200mm) and Panzershreks (capable of penetrating up to 160mm) definitely penetrated the M3 Grant’s 2 inch frontal and 1.5 inch side armour. 

With the tank on display I couldn’t resist getting some video of it, the surreal sight of light coming through both sides of the tank’s hull becomes sobering when you consider that Allied tanks faced the weapons which made the holes, in actual combat.

MECo.’s Malayan Emergency Display at Soviet Threat

A week or two ago (April 2022) we had the chance to catch up with friends from the MECo. group at the Soviet Threat event at the Hack Green Secret Bunker in Cheshire. Allen and Simon had an excellent display of weapons, uniform and personal kit from the Malayan Emergency (1948-1960) period and kindly talked us through it!

Thank you to Simon and Allen for giving us a detailed rundown of the display and kit. I find personal kit absolutely fascinating and MECo. are extremely knowledgeable and always put on an interesting display. In terms of weapons the display included a Bren Mk3, a Rifle No.5 and a very nice example of an Owen Gun. Below is another photograph of the Owen Gun and its magazine pouches, Allen had both a wooden and metal buttstock on display with the weapon.

Ukraine’s Molotov Cocktails

Almost as soon as the war began we started to see evidence of Molotov cocktail manufacture. The Ukrainian Ministry of Defense was keen to highlight and encourage it to show civilian resolve in the face of the Russian invasion and there’s been numerous news reports and tv news segments on Molotov production. 

Footage of Molotov manufacture spread across social media and was quickly seized upon by the world’s media. Videos from across Ukraine showed children, students, the elderly and ordinary people working makeshift production lines.

On the 26 February, two days after the Russian invasion women of Dnipro were featured on TV news making Molotov, shaving polystyrene for use as a thickening agent. In Lviv reports from 28 February suggested that 1,500 Molotovs were being made a day at just one makeshift factory. The Pravda brewery in Lviv also garnered attention with its employees and bottles turned over to Molotov production. The brewery manager said that they had produced 2,000 as of 18 March and shipped some to Kyiv. The former Ukrainian Minister of Internal Affairs Arsen Avakov even posed with Molotov Cocktail he’d made using a bottle of 1998 Château Mouton Rothschild. On 7 March the mayor of Lutsk, Ihor Polishchuk, estimated the city had a stockpile of as many as 7,000 Molotovs.

The morning after the invasion the Ukrainian National Guard posted a graphic showing how to make a Molotov and on the 28 February, the General Staff of the Ukrainian Armed Forces share some graphics suggesting the best places to hit Russian vehicles with Molotovs. And there have also been billboards posted with instructions on how to make a Molotov and another with a simplified graphic showing good spots to throw them. 

We have also seen a number of interesting delivery systems developed ranging from a medieval-inspired catapults to a pneumatic mortar. On 28 February we got our first video of a Molotov being used. With a short video showing a Molotov drive-by, with a Ukrainian’s throwing a Molotov against the rear of a Russian vehicle before speeding away. Since then a handful of other videos have shown Ukrainian civilians or Territorial Defence Force members destroying abandoned Russian vehicles and equipment.

Historically speaking, petrol-based improvised incendiary bombs have been used since the 1930s. Perhaps the first prominent use came during the Spanish Civil War. The weapons gained their nickname during the Winter War after Soviet foreign minister Molotov – a cocktail for Molotov. During the Second World War Molotov cocktails were one of the first weapons made by the fledgling British Home Guard, with them remaining in their arsenal well into the war. Both the British and US regular army’s trained with Molotovs during the early years of the war and they were certainly used by Soviet forces. Since then they have been used in countless riots, uprisings, revolutions, insurgencies and conflicts around the world.

How widespread the use of Molotov cocktails has been is pretty much impossible to know at this point. Despite having a comparative wealth of footage and photos from the ground we still only have a tiny picture of what is going on. It does appear that some have been used by the Territorial Defence Force units to destroy abandoned Russian vehicles and some have even been thrown at Russian vehicles – either as part of individual acts of defiance or as part of more coordinated attacks on Russian forces.

While Molotovs may seem futile in the face of a 40+ tonne T-72, they remain a cheap and effective weapon and checkpoints across Ukraine have been seen to have ready supplies of them. For the urban fighting that was expected in cities across Ukraine they make perfect sense as a plentiful, simple weapon which can be used to pepper Russian vehicles.

Making Mills Bombs

The No.36 or Mills Bomb was one of the longest serving grenades, developed during the First World War it originated from a Belgian design by Albert Dewandre and Capitaine Léon Roland. It was improved by a British industrialist, William Mills, who owned several metal forging factories.

A No.36 Grenade (Matthew Moss)

It entered service in late 1915 as the No.5 Mk1 and continued to be improved during the war with several iterations before it finally became the No.36M Mk1. We’ll look at the Mills bombs development more closely in a future video/article – today, with the help of some 1940s newsreels from New Zealand we’re going to look at how they were manufactured. While the newsreel doesn’t state the factories featured they were made by a number of factories including Anderson Engineering in Christchurch (these were marked with an “A” below the filler plug), Booth Mcdonald, of Christchurch (marked BM), Scott Brothers, also of Christchurch (marked SB), and Mason & Porter, of Mt Wellington, in Ackland (marked MP).

William Mills’ 1916 Patent for the grenade.

In the first newsreel, courtesy of Archives New Zealand (Weekly Review No. 70 (1943)), we see No.36 grenades being cast – the newsreel takes a slightly humorous approach of describing the process as a recipe – making ‘pineapples’ – a slang name by which grenades were sometime’s known. The factory is using the sand casting method with a pattern pressed into the sand and then removed. The two halves of the grenade’s body are pressed into sand, a pressed sand core could then be placed inside which would allow the grenade’s body to be poured hollow to allow room for explosives and detonator. If we again pause here we can see a machinist is centring and counter-sinking the filling hole’s first thread for its plug.

The footage includes a brief shot we see a woman factory worker drilling out the top of the grenade’s body and perhaps de-burring the side of the safety lever holder. In the next shot we see more machinists at work with one lady linishing the body of the grenade, removing imperfections from the casting on a grinder or polishing wheel and in the background some women a working on milling machines or drill presses.

At the very end of the film we can see the grenade bodies are stacked ready for the next phase of production. Sadly, we don’t see the threading of the filling hole or base in this film nor the painting or filling of the grenades.

In the second newsreel (Weekly Review No. 63 (1942)), however, which celebrates the production of 1 million grenades, we do seem more of the production process. In this short segment we see how the grenades are filled and how they work. We see the cast bodies of the grenades being transported on a conveyor after being shellacked to keep moisture out. If we pause here we can see this worker packing a case with “gascheck” discs and fuses.

Loading grenades, fuses and gas checks into a transit case (Archives New Zealand)

The gas check disc and a 7 second fuse was used when the grenade was being fired from a rifle’s cup discharger, while a 4 second fuse was favoured when throwing by hand. In this final clip we see the internals of a grenade – which was filled with just over 2oz of explosive through the round filling-hole (on the side opposite the safety lever) which was then screw plugged. The newsreel then concludes the grenade segment by showing the striker spring inside being compressed and a No.27 Detonator, with fuse, being inserted into the sectioned grenade.

We’ll examine more British grenades, including the No.36 in future videos and articles.

Vickers Gun In The Rhineland

In this final video of the Rhineland Campaign Weapons series we take a look at the little known role of the British and Commonwealth forces’ Vickers Guns. With the help of the Vickers MG Collection & Research Association we recreated a platoon line consisting of 4 Vickers Guns to recreate the Pepperpot tactics used during Operation Veritable – the western Allies’ invasion of Germany.

In this video we examine how Vickers Medium Machine Guns were used en masse to soften up enemy positions before Operation Veritable began and during the subsequent advance into the Rhineland. The Vickers was used alongside artillery, mortars and even anti-aircraft guns in what was known as a ‘pepperpot’ fire plan – where the focus was on weight of fire. The Vickers supported the advance through out the campaign and in this video we aimed to capture some of the feel of what those pepperpot bombardments might have been like – albeit on much, much smaller scale.

Using contemporary photographs and footage we recreated the gun pits, complete with overhead cover, pits dug to the original manuals and plenty of empty belts and belt boxes. Right down to the gun crews being badged up as Middlesex Regiment. Check out the comparison of our shoot and a contemporary photograph taken during the battle for Goch, 20 February 1945.

Below are some behind the scenes photos from the shoot taken by myself and Robbie McGuire:

A huge thank you to everyone who made the shoot possible, I’m very proud of what we were able to achieve with this shoot.
