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.
The Underwood Typewriter Company was a manufacturer of typewriters headquartered in New York City, New York. By 1939, Underwood had produced five million machines. In 1927 the company was reorganized into Underwood-Elliott-Fisher, which later became the Underwood Corporation. During WWII Underwood was one of the many companies who helped with the war effort. They produced about 8.9% of the total number of wartime M1 Carbines.

This Underwood M1 Carbine was built back in 1944. It has been Arsenal rebuilt but we do not know where due to the lack of an Arsenal Rebuild stamping. The rebuild may have been done in a U.S. friendly county as the current Keystone stock was used as a replacement stock in Korea. The receiver is stamped with the serial number in two places. This was done during Arsenal Rebuilds when a new rear sight was installed that blocked (all or partially) the original serial number.
This Underwood M1 Carbine  has seen some use but it should be a blast out at the range. Good luck.
