Colt Prototype "Zig-Zag" Root Revolvers

This video provides an expert-level overview of the rare Colt Model 1910 pistol, presented by Brownells from the Rock Island Auction Company. Speakers Keith Ford and Steve Ostrem detail its historical significance as a precursor to the 1911, highlighting key design elements such as its adjusted grip angle, screwless grips, internal plunger system, and slim hammer. The presentation emphasizes John Browning's direct involvement in its development and trials, showcasing a significant piece of American firearm history.

This prototype Colt Sidehammer 'Root' Dragoon represents an experimental design path Colt explored, blending features of the 1855 Sidehammer and 1848 Dragoon. It showcases a robust solid frame, a unique side-mounted hammer, and Elijah Root's patented 'creeping' loading lever with enhanced leverage. Though similar in size to the Dragoon, it was ultimately not chosen over scaling up the 1851 Navy design for the 1860 Army.

This video delves into a prototype Colt .380 pistol, offering a glimpse into its design and historical context. The content is presented through the "Forgotten Weapons" platform, known for its in-depth exploration of historical and rare firearms. The video's focus on a specific, likely uncommon, firearm model suggests a deep dive into its mechanics and development.

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.
