A refined and streamlined successor to the MP-38, the MP-40 made extensive use of metal stampings and synthetic materials to make a weapon robust enough to withstand the stress of war while being simple enough to manufacture to keep up with the demand. Nearly every armed branch and paramilitary organization in Germany made use of the MP-40, and many also found their way into the hands of opposition forces such as the French Resistance and Poland's Home Army, making it one of the signature weapons of the war. The stamped receiver of this one was manufactured by Merz Werke of Frankfurt (cos) in 1943, with the lower frame/trigger housing manufactured by Erma Waffenwerke (ayf) in the same year, and other parts from other sources. Blade front and two-leaf rear sight, with an alloy protective rib on the underside of the barrel, machined bolt with telescoping captive recoil spring assembly, a set of hard rubber grips and side panels on the trigger housing, and an underfolding stock. Included with the lot are six extra magazines and an unmarked, early war style, green leather three-cell magazine carrier with (empty) tool pouch.
