Forgotten Weapons
Published Aug 10, 2015The Czech Samopal vz. 26 was one of a family of submachine guns (the vz 23-26) that pioneered the use of bolts telescoped out forward over the barrel, allowing guns to have much better ratios of barrel to receiver length than before. The guns actually have quite a few interesting mechanical details, although in my opinion they fail to make it a particularly desirable gun for actual shooting.

Sten Mk5: The Cadillac of the Sten Family
Forgotten Weapons
Published Jun 17, 2024The Sten Mk5 (sometimes written Sten MkV) was really the Cadillac of the Sten series. It was designed in 1943, and featured a full wooden buttstock patterned after the No4 Enfield rifle, as well as an adjustable front sight and bayonet lugs for the Enfield. It has a wooden pistol grip as well (and early production examples also had a wooden vertical front grip). It was mechanically the same as the earlier Stens, simply with the fire control group moved forward to fit the pistol grip.
The Mk5 was not quite as insanely cheap and fast to make as the MkII and MkIII, but by the time it went into production British arms supply had largely caught up to demand, and they could afford to be a bit less economical. The Mk5 was really much better handling than earlier models, and was well liked, seeing combat as early as the invasion of Normandy in June 1944. In total, 527,428 of them were produced and they remained in service until the adoption of the L2 Sterling submachine gun in 1957 (and they were not completely phased out until at least the late 1960s).

Sten MkIII: A Children’s Toy Company Makes SMGs
Forgotten Weapons
Published Jun 5, 2024Lines Brothers was a company in the UK that made sheet metal childrens’ toys prior to the war. When production of the Sten guns began, Lines Bros was a parts subcontractor. Their engineers analyzed the design alongside the machinery the company had available and redesigned a version of the Sten that they could make very quickly and cheaply in-house, by replacing the tube receiver with a rolled and spot-welded piece of sheet steel. Their first order came in January 1942, to a whopping 500,000 guns, which were designated the MkIII.
The Sten MkII and MkIII were produced simultaneously, and Lines Brothers was the only producer of the MkIII. Ultimately they got three contracts, although the second one was cancelled before it was completed and the third was never begun. A total of 876,794 MkIII Stens were made by September 1943. Once submachine gun production caught up with British needs, the MkII was found to be the superior of the two designs and only it remained in production.

Sten MkII: Just When You Thought It Couldn’t Get Simpler
Forgotten Weapons
Published May 29, 2024The Sten MkI had barely been approved for production when the Sten MkII was born. Initially requested to produce a version of the gun suitable for paratroopers, in March 1941 Harold Turpin redesigned the front end of the Sten to have a quickly detachable barrel and a rotating magazine well (for compact storage). This new model was tests in late June and early July, approved for use, and contracts for it were issued in August 1941.
Named the MkII, this model of the Sten would quickly become the standard, and it was ultimately produced by six major factories (with the assistance of hundreds of subcontractors) on three continents to the tune of 2.6 million examples made. In addition to the barrel removal, the new model has a simpler front sight, simpler stock, and a revised bolt locking notch (upward, instead of downward like on the MkI).

Sten MkI & MkI*: The Original Plumber’s Nightmare
Forgotten Weapons
Published May 22, 2024The Sten gun was designed by RSAF Senior Draftsman (sorry, Draughtsman) Harold Turpin in December, 1940. He sketched out a simple trigger mechanism on December 2, showed it to Major Reginald Shepherd the next day, and then finished out the rest of the submachine gun design that week. The first prototype gun was completed on January 8, 1941 and it was tested by the Small Arms School that same month. The design was approved for production (alongside the Lanchester) March 7th, 1941 and the first of 300,000 Sten MkI guns was delivered to the British military on October 21, 1941. The MkI and MkI* Stens were all manufactured by the Singer sewing machine company in Glasgow, with three contracts for 100,000 guns each issued in 1941.
The Sten was the British response to a dire need for a large number of cheap infantry weapons, and it served that purpose well. The MkI was quickly followed by a somewhat simplified MkI*, which discarded the unnecessary flash cone and the wooden front grip. An even simpler MkII optimized for mass production followed, along with a MkIII. As the end of the war approached the MkV was introduced which had much improved handling, and it would remain in service until the 1950s, when it was finally supplanted by the Sterling.

Madsen M50: From the Korean War to Star Trek
Forgotten Weapons
Published May 1, 2024During World War Two, Madsen (DISA) manufactured a licensed copy of the Finnish Suomi (see: Danish M1941 Suomi SMG). When the war ended, they wanted to replace this with a more modern, inexpensive design of their own. The result was the Model 1946 Madsen, a creative clamshell design of stamped parts. It is a very simple blowback, open-bolt 9x19mm SMG that perfectly fit the post-war era. The M46 version was sold to a few countries, and after some continued development and refinement the M50 version was demonstrated to a public audience in November 1950. This pattern was even simpler than before, and proved a popular gun for many unaligned countries in Central and South America and Southeast Asia — so much so that it remained in production until the 1980s. A bunch were imported into the US in the 1950s and 1960s, and they found a home in the movie industry, where they were often used in fantasy/sci-fi films to avoid having guns that would be recognized by American movie audiences.

M1 Thompson: Savage Simplifies the SMG
Forgotten Weapons
Published Apr 28, 2024The Thompson submachine gun struggled to find a market when it was originally produced, with the first batch of 15,000 Colt-made guns not finally all selling until the late 1930s. By that time, the clouds of war were gathering, and demand for submachine guns finally began to really grow. The US military had some Thompsons, and the British began buying as many as they could. The US wanted to increase production, and that meant simplifying the gun, both to reduce cost and to increase manufacturing efficiency. Talks to this end began in late 1941, and by February 1942 the engineers at Savage had a prototype of what would become the M1 Thompson.
This new version simplified almost every element of the gun, but most significantly it replaced the 3-piece Blish lock bolt with a solid one-piece affair that just worked as a normal blowback action. Unnecessary elements like the vertical front grip, Cutt’s compensator, quick-detach stock, and fancy contoured selector levers were discarded. The adjustable Lyman rear sight was replaced by a single metal tab with an aperture (quickly given a set of protective wings though, as the tab alone proved too fragile). The recoil guide rod was simplified, the oiling pads inside the receiver removed, and a simpler recoil buffer designed. The capability to use drum magazines was also discarded, and a new 30-round box magazine took their place.
The M1 was adopted in the spring of 1942, and July saw the first major delivery, of 48,000 guns. Simplification work continued, however, and by the end of October a yet-simpler M1A1 pattern was adopted. This model replaced the hammer mechanism with a fixed firing pin. As a result, M1 production lasted only about 5 months. A total of 285,480 M1 Thompsons were made, but most of these were retrofitted to M1A1 configuration by simply swapping in the simpler new bolt. Finding intact M1 configuration guns is rather unusual today as a result.

Chinese Type 50 PPSh: Founding “Gun City” in Manchuria
Forgotten Weapons
Published Apr 12, 2024One of the first new weapons adopted and used by the Chinese Peoples’ Liberation Army after the Communist victory in the Chinese civil war was the Type 50, a copy of the Soviet PPSh-41. The story of its manufacture begins at the Japanese-occupied Mukden Arsenal. It was briefly occupied by the Soviets in 1945 before coming under control of the CCP. It was a huge manufacturing complex at the time, making artillery, small arms, ammunition, and more. A Nationalist bombing raid in 1949 led to the production being distributed among three separate smaller facilities, and the small remote town of Bei’an was chosen to become the new small arms factory site.
The town became so heavily focused on weapons manufacture that it gained the nickname of “Gun City”. The factory was formally named #626, and given the cover name of Qinghua Tool Company. It initially began with production of the Type 38 Arisaka, Type 24 Mauser (the Chiang Kai Shek rifle), the M1 Carbine (a failed project), and the Type 50 copy of the PPSh. In the spring of 1951 in response to UN advances northward in Korea, production was ordered to scale up on the Type 50, to 7500-9000 per month. This took a couple of months to achieve, but in June 1951 the first large shipment of the guns left the factory, and by December 1953 a total of 358,000 had been made. At that point, production shifted to the Type 54, a copy of the PPS-43.
The Type 50 is a close copy of the Russian Shpagin, but differs in a couple of details. The Chinese used a rear aperture sight, and the sights were placed slightly farther forward than on Russian guns. They are also generally very well made — better than most Russia wartime examples.

Patchett Machine Carbine Mk I: Sten Becomes Sterling
Forgotten Weapons
Published Feb 14, 2024The Patchett Machine Carbine Mk I is the predecessor to the Sterling SMG. It was developed by George William Patchett, who was an employee of the Sterling company. At the beginning of the wear, Sterling was making Lanchester SMGs, and Patchett began in 1942 working on a new design that was intended to be simpler, cheaper, and lighter than the Lanchester. He used the receiver tube dimensions from the Sten and the magazine well and barrel shroud from the Lanchester. His first prototypes were ready in 1943, but it wasn’t until early 1944 that the British government actually issued a requirement for a new submachine gun to replace the Stens in service.
The initial Patchett guns worked very well in early 1944 testing, which continued into 1945. It ultimately came out the winner of the trials, but they didn’t conclude until World War Two was over — and nothing was adopted because of the much-reduced need for small arms. Patchett continued to work on the gun, and by 1953 he was able to win adoption of it in the later Sterling form — which is a story for a separate video.
The Patchett was not used in any significant quantity in World War Two. At most, a few of them may have been taken on the parachute drops on Arnhem — there are specifically three trials guns which appear referenced in British documents before Arnhem, but are never mentioned afterwards (numbers 67, 70, and 72). Were they taken into the field? We really don’t know.

Ero: The Croatian Uzi (With Israeli Help?)
Forgotten Weapons
Published Jan 3, 2024The best of the submachine guns made in Croatia during the Homeland War was the Ero, made by a company called Arma. The Ero is a basically perfect, parts-interchangeable copy of the Israeli Uzi that was developed in 1992 and adopted into Croatian Army service in 1993. The only really distinguishable difference between the Ero and Uzi is the Ero’s use of Croatian-language selector markings (and receiver markings). Between 15,000 and 20,000 were produced, and they remained in service long after Croatian independence was secured. They were issued to vehicle crews, military police, special forces, and reconnaissance units.
Arma was a subsidiary of a major Croatian engineering firm, and after the Ero production it developed the APS-95 Croatian AK (which is a story for another video). They were a very competent company, but the details and quality of the Ero are so good that I believe it must have been made with tacit or explicit assistance from Israel. Croatia does have a strong Jewish community, and there were rumors during the war that the technical data package for the Uzi did find its way into Croatia. There is no official acknowledgement of this happening, but it would certainly not be hard to believe. But however the development happened, the result was a very high quality submachine gun.

Weirdest of the French Trials SMGs: the EROP 1954
Forgotten Weapons
Published Dec 15, 2023“EROP” was a small company based in Paris, which produced about 18 submachine gun prototypes between 1954 and 1956. These were submitted to French military trials in several different configurations first in 1954 and later in 1956, and none of them were given any further consideration after that.
Mechanically, the EROP guns are closed-bolt and striker-fired, using modified MP40 magazines (and chambered for 9mm Parabellum). They use a small square-profile tubular receiver, and several (including this particular one) have a very perplexing buttstock system that I really can’t figure out.
Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film this unique SMG for you!

MKb-42(H) Assault Rifle with ZF-41 scope
Forgotten Weapons
Published 31 Aug 2014The MKb-42(H), or Maschinenkarabiner-42 (Haenel), was the first production iteration of the German Sturmgewehr. It was chambered for the then-new 8x33mm kurz cartridge, and fired both semiauto and full-auto from an open bolt. Approximately 11,000 of these were made before production changed to the closed-bolt MP43.

MGD PM9 Rotary-Action Submachine Gun
Forgotten Weapons
Published 23 May 2017The PM9 was an interesting an unique submachine gun designed by Louis Debuit for the French firm Merlin and Gerin (hence the MGD name – Merlin, Gerin, Debuit) in the late 1940s and early 50s. The design was intended to provide a very compact package, which it did with a very short action, folding stock, and folding magazine.
The PM9 uses a delayed blowback action, and the delaying is done by a rotating flywheel-type block and clock spring. The bolt and flywheel act somewhat like the piston and crank in an engine. As the bolt (piston) moved rearward in a straight line, it forces the flywheel (crank) to rotate because the two are connected. In the case of the PM9, the connection is a nub on the flywheel that rides in a vertical slot in the bolt. The flywheel is pushing against the clock spring to rotate, and the combination of the its inertia and spring pressure keep the bolt closed long enough for pressure to drop to a safe level. The rotary action allows this to be done in a much smaller package than typical submachine guns.
The PM9 was initially chambered for 7.65 French Long, but quickly changed to standard 9mm Parabellum for the production models. It used the same magazine as the German MP38/MP40, giving it a 32-round capacity. In addition to the model with a skeletonized folding stock, the PM9 was also available with a fixed wooden stock and either short barrel of long carbine barrel. A relatively small number of guns were produced in France in 1954 and 1955, but they failed to find commercial success. In 1956 the German Erma company acquired a license to build the PM9, but abandoned the idea after making a few prototypes.

Gnome et Rhône R5: A Foiled Communist Arms Plan
Forgotten Weapons
Published 26 Apr 2023The R-5 was a French-made copy of the Sten produced after the 1944 liberation of France. It was built by Gnome et Rhône, a French company best known for making aircraft engines. The Sten was familiar to French forces, as many had been supplied as military aid to the Free French as well as Resistance organizations — and it was also a simple and cheap weapon to make.
In the aftermath of Liberation, there was a lot of political jockeying for power in France. Many different factions had armed themselves during occupation, from the far right to the far left, and everyone wanted to be in a position of power in post-war France. Gnome et Rhône was contracted to make 20,000 of the R-5 submachine guns specifically for the PCF, the French Communist Party (Parti communiste français). The Gaullist government found out about the production and took the guns for itself before any reached the PCF.
The R-5 (named because it was produced in Limoges, in the 5th Region of France as organized during the Resistance) was parts-interchangeable with the standard British MkII Sten, despite having a number of unique features. The R5 used a barrel 60mm (2.5 inches) longer than the standard Sten barrel, a solid wooden stock of the same shape as the MkII, and a vertical front grip inspired by the Thompson. Although missing on this example, it also had a rotating receiver cover that could be used to lock the bolt in the forward position.
Of the 20,000 R-5s ordered, only 8,000 were delivered as best we can tell today. They were used by the military within France and also in Indochina and even into Algeria. In the immediate postwar years France was heavily dependent on US and UK war material, but wanted to equip a larger force than the Anglo-American allies were planning to supply. The R-5 made a useful interim weapon while the French arms industry reestablished itself and eventually developed the MAS-49 rifle family and the MAT-49 submachine gun.
