37mm MK1 37x252mm casing for Soviet 61K AA gun by British colonial Pakistan
See more information below...
Very interesting 37mm cartridge case that we believe was made by British colonial Pakistan for use in their Soviet made (captured) 37mm 61-K anti-aircraft guns. Headstamp shows 37mm MK1, and is marked POF (Pakistan Ordnance Factories). This 37x252mm casing is made of brass and is in good condition. Markings can be clearly seen on base of case, and there is an ink stamp on the side of the case that can faintly be seen and read.
