Colt 1911's in caliber .38 Super were ordered by the Office of Strategic Services OSS. This is the original ammunition.
Only 3 manufacturer lots are known 5001, 5002 and 5003. These boxes are clearly marked on the front 5002. Cartridges are clean looking brass cases, FMJ projectile and a standard commercial head stamp in a military kraft colored box. These boxes came out of the sealed spam can from the original wooden crate.
