Müller 1902 Prototype Pistol (Video)


Bernhard Müller designed this locked-breech pistol in 1902, seemingly a hybrid of the Luger and P38 (of course, the P38 did not exist at that time). It appears to use a modified Luger magazine and is chambered for the 7.65mm Luger cartridge. The grip is very much Luger-like, in part because the use of […]

Hudson .30 Cal Machine Gun Toolroom Model (Video)


Robert F Hudson developed a series of machine guns for the US Navy during the 1920s and 1930s, including this .30 caliber example as well as .50 caliber and 1.1 inch versions. What makes these guns unusual is both the attempted use of a counter-balanced system to eliminate felt recoil and also the standard […]

Bjorgum 1905 Norwegian Prototype Pistol (Video)


Niels Bjorgum was a Norwegian artist-turned-gun-designer who decided to try his hand at handguns for the Norwegian military. His design work ran from 1894 until 1921 or so, starting with long guns but later turning to handguns. He was able to convince the Norwegian government to sponsor his work, largely because he was one […]

Magazine for an XM19 SPIW Flechette Rifle

The XM-19 was one of a series of Special Purpose Infantry Weapon (SPIW) prototype designs in the 1960s and 70s – a project which was attempting to increase the hit probability of infantry weapons. Several different approaches were tried to this end, including firing multiple cartridges […]

Terni M91 Carcano Semiauto conversion (Video)


This rifle started out its life an a normal M91 Carcano long rifle, before being converted into an experimental self-loader by the Terni Arsenal. Rather than adding a gas piston to the barrel, Terni engineered a short recoil system. The barrel and bolt recoil together about a centimeter (3/8 inch) upon firing. Instead of […]

Thompson SMG in 30 Carbine (Video)


When the US military released a request for what would become the M1 Carbine in 1940, the Auto-Ordnance Corporation offered up a Thompson submachine gun simply rechambered for the new .30 Carbine cartridge. This entailed a new magazine, a receiver modified for the longer magazine, and a new barrel and bolt face – but […]

Spanish 8×33 Mosqueton CB-51 Prototype (Video)


The Spanish military, like many others, was quite interested in developing a new semiautomatic or selective fire combat rifle after World War II. Franco’s political ties to Germany (combined with Spanish neutrality in the war) gave them unusually good access to German arms designs, and the Spanish experimented with several variations on the StG-44 […]

Detailed Photos: Mannlicher 1901/04 Carbine

One of Ferdinand von Mannlicher’s very last firearms was an experimental 1901/04 carbine, scaled up from its original pistol cartridge to a new 7.63x32mm intermediate-sized cartridge. I had a video on one of these very scarce carbines from a previous Julia auction, and also took a bunch of detailed photos of the gun disassembled. Mechanically, […]

Great Article on the Dror LMG


Terry Edwards has graciously offered to let me repost the excellent article he wrote for Small Arms Defense Journal. It’s a two part PDF, and I have posted both parts below.

If you are interested in this little-known developmental side track of the Johnson LMG, you should definitely have a look – and the same […]

Hagen Prototype Semiauto Rifle (Video)


The Hagen (more information here) is an early semiauto rifle designed by a Norwegian, manufactured in the UK, and tested by several different militaries – but adopted by none. It uses a long stroke gas piston and a two-lug rotating bolt to operate. Compared to other contemporary rifles, it was a quite light and […]
