Mars Automatic Pistol: Ye Olde Hand Cannon

The Little Tom is highlighted as the world's first Double Action Only (DAO) automatic pistol, featuring a unique bi-directional magazine loading system. Its barrel disassembly involves pushing it back to release an oval lug from a dovetail slot. The internal mechanism demonstrates a specific trigger bar and hammer interaction for DAO operation.

The Mendoza Model 1934 LMG is a rare Mexican-designed firearm from the interwar period. Its unique features include an offset magazine to the right, allowing for a centered sight radius, and a distinctive pull-back magazine release. The design incorporates a rotating bolt, reminiscent of the Lewis gun or M60, and offers adjustable gas operation with a three-position fire selector.

This video showcases a rare four-barrel mule ear custom rifle from the 1850s, manufactured in Ashtabula, Ohio. The rifle features four .36 caliber rifled barrels and a distinctive 'mule ear' hammer mechanism with side-mounted hammers. It also incorporates primitive eye protection shields to guard against powder residue and cap fragments.

This video from Forgotten Weapons details the complex journey of Lithuanian rifles following WWII. Due to successive Soviet and German occupations, these arms were scattered, ending up in various national arsenals, with partisans, and eventually dispersed globally to regions like China, Vietnam, and Africa as part of post-war arms caches. The expert analysis highlights the geopolitical impact on small arms distribution.

This video showcases the rare 14-barrel double Nock volley gun, a unique firearm featuring two clusters of seven rifled barrels each. It highlights the gun's specialized features, including a vertical front grip for handling its significant weight and dual triggers for independent firing of each cluster. The demonstration also covers the specialized seven-chamber powder throw for simultaneous loading and the modular design allowing conversion to a seven-barrel configuration.

The 2.7mm Kolibri is the world's smallest centerfire cartridge, firing a 3-grain projectile at 650 fps with 3 ft-lbs of energy. Approximately 1,000 units were produced before WWI, ceasing due to wartime production shifts. The pistol, weighing 7.7 ounces loaded, features the 'FP' monogram for designer Franz Pfannl and was sold in a presentation case.

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.
