Originally 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. This example was manufactured post-WWII for commercial sale. Blade front and 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, and a fixed buttstock. No military inspection marks are present. The bolt is of the M1A1 pattern, with a fixed firing pin, and the interior of the receiver is marked "QFM122A".

Excellent, with 95% plus original blue finish, showing some light wear and handling marks overall. The stock is also excellent, with some light dings and dents. Mechanically excellent.
