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 of its original NPM parts which include its Underwood marked barrel. Underwood supplied barrels for NPM. The metal was refinished during the rebuild and the stock has since been refinished. This is a good looking M1 Carbine to add to the collection and take out the range. Good luck.
