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. Blade front and fixed peep rear sights, with a straight forearm under the smooth barrel, "FJA" and "GEG" inspection marks on the frame along with the address markings and model nomenclature, ribbed pistol grip and a fixed buttstock. The bolt is the simplified M1 design, with the Blish lock eliminated and the cocking knob moved to the side, but still retaining the articulated firing pin. With a tan canvas sling.

Very fine as professionally refinished, showing 95% of the dark blue finish, with some edge wear, handling marks, and covered up dings and pitting. The wood is also very fine, with a number of dents and scuffs overall, along with a crack in the front of the buttstock. Mechanically excellent.
