1944 National Postal Meter M1 Carbine .30 Carbine

WWII U.S. Military Prime Contractor M1 Carbine

The M1 Carbine was designed by Winchester and produced by ten primary government contractors during World War II to provide a lightweight, highly maneuverable shoulder arm for rear-echelon troops, non-commissioned officers, and support personnel. This example was manufactured by National Postal Meter (NPM) in Rochester, New York, one of the more sought-after commercial contractors that pivoted facilities to aid the war effort. Chambered in .30 Carbine, this historic firearm features a short-stroke gas piston system, an aperture sight layout, and a lightweight hardwood stock. Serial number 4265301 falls directly into NPM's primary assigned serial block (4,075,000 to 4,431,094), placing its production in the late 1943 to early 1944 timeframe. This package comes outfitted with an authentic web sling, a 20-round magazine, and a vintage cleaning/tool kit.
