Our Assessment: The M1 Carbine was developed and produced after WWII started. Over 6 million were made by a number of U.S. companies to assist with the all out war effort. The M1 Carbine was widely issued to U.S. Military Forces which numbered over 16 million during WWII. The M1 Carbine contributed greatly to U.S. efforts during WWII.
National Postal Meter (NPM) was one of several contractors who tooled up during WWII to produce M1 Carbines in support of the war effort. NPM rushed into the war effort as did other companies with no firearms background. At the time of their first contract NPM 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 building’s concrete floor and literally shooting under the feet of the production line. Despite these issues NPM was able to produce about 6.8% of the total number of WWII M1 Carbines.

This National Postal Meter M1 Carbine was built back in 1943. It has been rebuilt using a mix of USGI parts but still retains some NPM parts. The metal and wood have been refinished so the rifle looks impressive for a military service rifle that is almost 80 years old. This is a good looking M1 Carbine that should be a lot of fun to take out the range…once you add a magazine. Good luck.
