1867 Werndl Military Rifle

The Steyr M1912/16 Repetierpistole is an extremely rare, full-auto variant of the standard M12 pistol, developed for the Austro-Hungarian military during WWI. It features a 16-round fixed magazine, a high cyclic rate of 1200 RPM, and was designed to be used with a shoulder stock. Production was limited to 200 units, with very few surviving today, making authentic examples highly sought after and fakes common.

The Frommer Pistolen-MG Model 1917 was an experimental Austro-Hungarian machine pistol, a functional copy of the Italian Villar Perosa, developed by FEG. It modified Frommer Stop pistols to fire from an open bolt, mounted them on a tripod, and used 25-round magazines in .32 ACP. Despite its unique design, it was not adopted due to concerns about reliability with long magazines and the cartridge's limited effectiveness.

The Steyr 1893 Gas-Seal Revolver was an Austrian military prototype tested before the Rast & Gasser 1898, featuring a unique Pieper-style gas-seal mechanism where the cylinder moves forward. Produced in limited numbers, it chambered 8mm and had variations in cylinder design. Despite its aesthetic appeal and complex 'strawed' internal finish, a heavy double-action trigger pull likely prevented its adoption.

The Frommer 1901 is a large, long-recoil pistol designed by Rudolf Frommer, featuring a rotating bolt and an integral 10-round magazine fed by stripper clips. Chambered in 8mm Roth, it was submitted for US military trials in 1904 but ultimately rejected due to its caliber, feeding mechanism, and lack of a clear empty-chamber indicator. Its complex design includes two separate recoil springs and a unique disassembly process.

This expert-level analysis from Forgotten Weapons provides a detailed, slow-motion examination of the Roth-Steyr 1907 pistol. It highlights the unique locked breech, rotating barrel, and short recoil action, comparing its half-cock mechanism to modern firearms like the Glock. The review covers its clip-fed nature, striker indicator, and historical context as a standard handgun for the Austro-Hungarian military in WWI, noting its comfortable shooting characteristics despite the 8mm Steyr caliber.

The Frommer Stop (1912) is a unique pistol employing a long recoil action, a complex mechanism where the bolt and barrel lock and travel rearward together. High-speed footage reveals the intricate firing cycle, including the barrel's forward movement for ejection and the bolt's subsequent return. This Austro-Hungarian design, featuring a 3-lug rotating bolt, offers a comfortable shooting experience despite its uncommon action.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
