A refined and streamlined successor to the MP38, the MP40 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 MP40, 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. "MP40/ayf 43/3944W cnd" (Erma) marked on the rear receiver end cap and "44/cos" (Merz Brothers) on the receiver tube. The left of the barrel, barrel nut, bolt, firing pin, receiver tube, underside of the trigger housing and underfolding shoulder stock are stamped with full and partial matching serial numbers and the appropriate Waffenamt proofs. 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, the traditional dark red bakelite lower receiver cover and dark brown grips. Two extra magazines are included; all included magazines are unmarked.

Very fine, retains 75% refinished blue finish over scattered light pitting and smooth brown patina on the balance with some scattered light handling marks. The grips and receiver covers are very fine with some light scratches and handling marks. Mechanically excellent.
