Developed in 1942, the U.S. 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. "AOC" marked blade front and Lyman fixed peep rear sights, with a straight forearm under the smooth barrel, address and model nomenclature markings on the frame, simplified selector and safety levers, grooved pistol grip, fixed buttstock and a tan canvas sling. No military inspection marks are present. The bolt is of the M1A1 pattern, with a fixed firing pin, and, as is proper for the M1, there is no provision for an oiler or Blish Lock. The barrel has a half inch of internal threading at the muzzle; while not explicitly documented, this modification is chiefly associated with the use of restrictor devices to allow blank firing ammo to produce sufficient back-pressure to properly cycle the weapon. Included with the lot is a modern nylon soft case and an extra magazine.

Excellent, with 97% plus original parkerized finish, showing mild handling marks and wear overall. The wood is very fine, with light storage dings and scuffs. 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) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
