A Very Rare US Military WWII National Postal Meter M1 Carbine 30. Carbine Semi Auto Rifle in good to very good condition with a bright and defined bore. The action appears to function properly with heavy patina to the original finish and some cosmetic blemishing to the stock. The rifle comes with US marked canvas double magazine stock pouch, sling, and extra magazine. The National Postal Meter M1 Carbine is a collectible WWII U.S. military firearm produced under government contract during the Second World War. The M1 Carbine was designed as a lightweight .30 caliber semi-automatic arm for troops who needed more range and accuracy than a pistol, but less weight and recoil than a full-size service rifle. National Postal Meter, based in Rochester, New York, was one of the wartime contractors selected to help meet the massive demand for M1 Carbines. The company produced approximately 413,017 carbines, making it a smaller-production contractor compared to major makers like Inland and Winchester. Today, National Postal Meter carbines are desirable to collectors due to their WWII production history, contractor markings, and relative scarcity among U.S. M1 Carbine manufacturers.
