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, "GHD" inspection marks on the frame along with the address markings and model nomenclature, "AOC" on the underside ahead of the magazine well, ribbed pistol grip and a fixed buttstock. The receiver is numbered "304535" and the trigger housing is numbered "16532", with a faint marking hand-scratched into the left side of the receiver. 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. Includes two extra magazines in what appears to be original packaging. Provenance: The Allan Cors Collection
