Book Review: Systeme Lefaucheux

Pinfire cartridges were a crucial transitional technology due to limitations in early industrial brass drawing capabilities, predating efficient production of modern metallic cases. Casimir Lefaucheux patented the system in 1835, leveraging existing percussion hammer mechanisms. Eugene Lefaucheux later industrialized it in the 1850s, coinciding with advancements in brass metallurgy and case drawing.

Samuel Pauly's 1812 invention of the self-contained cartridge revolutionized firearms by introducing a brass-based, paper-cased round with a fulminate primer. This system offered significant advantages over muzzleloaders, including faster loading, easier cleaning, and consistent power. Pauly's workshop also fostered innovation, influencing key figures like Nikolaus von Dreyse and Casimir Lefaucheux, who developed groundbreaking firearm technologies.

This video from Brownells Gun Tech™ features a fascinating look at unique and collectible firearms that disguise themselves as everyday objects. Host Keith Ford, joined by Joel Colander from Rock Island Auction Company, explores a Frankenau Purse Pistol from the late 1870s that fires pinfire cartridges, a single-shot percussion cap pistol hidden within an ornate object resembling a Faberge egg, and a modern-production cane gun from Lebeda Engineering concealing a tiny 5mm pinfire revolver. The segment highlights the ingenuity of "concealed carry" throughout history and into the present.

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.
