WWII U.S. M37 Army Air Corps/Force Technician 3rd Grade's Wool Service Shirt

This original WWII U.S. M37 wool service shirt belonged to an Air Corps/Force technician 3rd grade photography specialist. We know by the sleeve insignia that he served in the Army for three years, with two of those years spent overseas. This shirt is the enlisted man's version, without epaulettes. Unfortunately, its size could not be located and the manufacturer's tag has been removed. It shows signs of use, including a missing button, but is still in good condition.
