This short showcases an extremely rare and valuable 100-round 'C' drum magazine for the Thompson Submachine Gun, with an original Colt version fetching $24,000 at auction. The video highlights the impressive size and weight of the drum, comparing it to standard stick magazines, and briefly touches on the Thompson's mechanical features like the Blish lock and select-fire capability.

This ASMR short focuses on the Thompson Model 1928, also known as the 'Chicago Typewriter'. It demonstrates the action cycling, controls (fire selector and safety), and the Lyman ladder sight. The video also shows loading .45 ACP snap caps and highlights receiver and manufacturer markings, emphasizing the firearm's historical significance and mechanical operation.

This Q&A episode from Forgotten Weapons covers a wide range of topics, including international travel and customs, personal travel aspirations, and specific firearm-related discussions. Topics delve into ammo construction (half-brass), the rarity of closed-bolt SMGs and hexagonal barrels, economical machine guns, the FN49 in different calibers, sniper rifles for fictional Elbonia, and historical firearms like the 8mm Lebel Maxim and Ethiopian oddities. The discussion also touches on comparisons between the WWSD and M16, ideal French rifles for smokeless powder, a 2-Gun match choice (Carcano, Enfield, Arisaka), the CETME AMELI's limited success, a sought-after but elusive firearm, cartridge design theories, seemingly contradictory designs (M3 vs. PPSh-41), the manufacturing process of stamped parts, ideal firearm pairings for matches, a hypothetical Pedersen vs. Johnson scenario without the Garand, 'non-real' actions like Blish, printed magazines for rare guns, the future of 9mm and 5.56mm, the biggest military lesson from WWI, and whether Simonov saw an RSC rifle. The episode concludes with a fun question about unlimited ammo from Santa.

The Thompson Model 1928A1 is a classic submachine gun distinguished by its finned barrel for heat dissipation and Cutts compensator to reduce muzzle climb. It features a unique last-round bolt hold-open and the Blish lock system, differentiating it from the simpler M1A1. The 1928A1 accepts 30-round stick magazines or larger drum magazines.

The M1A1 Thompson represents a significant simplification of the iconic WW2 submachine gun, designed for mass production. Key changes include the removal of the Blish lock in favor of a straight blowback action and a fixed firing pin, reducing machining time and cost. External modifications like a fixed buttstock and simplified grip further streamlined production, making it a more efficient military firearm.

This video compares the 1921 and 1928 Thompson submachine guns, highlighting their differences in rate of fire and controllability. The 1921 model fires at 900 RPM, making it difficult to control, while the 1928 model was modified to a slower 650 RPM for improved handling. The discussion also covers magazine variations and the innovative Blish lock mechanism.

This video explores a unique "Ross" Semiauto Prototype Rifle from approximately 1915, featuring a custom action based on the experimental Blish-Lock system. While utilizing furniture and a magazine from a Ross rifle, the core mechanism is a novel design that was also tested in early Thompson submachine guns. The Blish-Lock's principle of using friction between dissimilar metals under pressure proved problematic in high-pressure rifle cartridges, leading to its eventual abandonment for simpler blowback designs.
