I was fortunate enough to find this ammo box (can) at a local Rod & Gun swap meet,
Twin Cities Army Ammunition Plant, Cal .30 Ball M2 linked “FOR GUN FUNCITON ONLY”.
I suspect the ammunition packed in this can was loaded to very exact standards and was used in house to routinely check gun function & sighting for MGs used in testing samples of ammunition taken from daily production.
The manufactures mark is stamped into metal below the lid closer: “OSH. STPG. CO.” I checked MIL-HDBK-1461A (Manufacturers & abbreviations) and a listing of ammunition can makers but I cannot find this maker listed.
Can anyone identify the manufacturer “OSH. STPG. CO.” ?
