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, ribbed pistol grip and a fixed buttstock. Marked "S" on the receiver and bolt, the former also bearing "FJA", "GEC" and "crossed cannon" inspection marks. The slots for the drum magazine have been eliminated, with the simplified drum and post style selector/safety switches on the trigger housing and a matching number on the underside of the triggerguard. The bolt is the side-charging M1 design, sans oiler and Blish lock, with an articulated firing pin. Includes two tan canvas "USMC" marked magazine pouches.

Very fine, with 95% of the arsenal refurbished parkerized finish, showing wear along the high edges and scattered handling marks overall. The wood is also very fine, with mild scattered dents and scuffs. Mechanically excellent.
