Developed in 1942, the M1 Thompson was a streamlined version of the classic Thompson SMG, intended to simplify the weapon and speed the manufacturing process. While frills were trimmed, the M1 was still a classic "heavy metal" SMG, constructed from machined steel with fine hardwood furniture. This example was manufactured post-WWII as a registered transferable commercial machine gun. Blade front and Lyman-style folding rear sights, with a set of 1928A1 pattern furniture (fixed buttstock) and standard address markings and model nomenclature. The bolt is the simplified M1A1 design, with the Blish lock eliminated, cocking knob moved to the side, and a fixed firing pin. Included with the lot are three stick magazines and a "U" marked Auto-Ordnance "L" type 50-round magazine.

Very fine, with 90% plus of the original blue finish, showing bright edge wear and mild handling marks overall, with some play in the rear sight base. The refinished wood is very fine, with some scuffs/tool marks concentrated around the screws. The rear grip is a bit undersized at the frame, and the buttstock at the buttplate. Mechanically excellent. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) that is classified as a "Curios or Relic" as defined in 27 CFR, 478.11. These weapons are still subject to the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
