Our Assessment: This National Postal Meter (NPM) M1 Carbine was built back in 1943. At some point it was rebuilt using a mix of USGI parts but the Marlin barrel appears to be original. NPM did not make barrels. Marlin was one of the 3 companies that supplied NPM with M1 Carbine barrels. The metal was refinished nicely during the rebuild keeping most of the markings intact. This is a nice looking M1 carbine that will add to your collection.
Here is some interesting information on NPM from “A week after America’s entry into WWII, National Postal Meter and the Todd Corporation partnered to start the Rochester Defense Corporation. It was this company that negotiated for the contract to produce M1 Carbines. Shortly after the approval of their 2nd contract, but before production started, Rochester Defense Corporation was dissolved and its assets merged into National Postal Meter. At the time of their first contract, the company had no tools, no employees, and no location for building carbines. National Postal Meter’s test fire range was built by raising the floor of the carbine manufacturing plant three feet above the buildings concrete floor and literally shooting under the feet of the production line…Performance testing gave them the highest rating in adverse conditions. (NPM) made no barrels…National Postal Meter Company changed the name of their company to Commercial Controls Corporation on April 26, 1944. The same month they ceased carbine production. The 239 Commercial Controls M1 Carbines were assembled from leftover parts and provided to U.S. Army Ordnance in August 1945.”
