Headstamp ID-South Korea on 30 Carbine


Can anyone confirm the manufacturer of this headstamp? Appears Korean does it not?

Sorry forgot to add: On a 30 Carbine cartridge.


Yes, it was made in South Korea by Poongsan Metal Manufacturing Company Ltd.

Headstamp reads 제 1 조 78.

I had thought that this should be a korean equivalent for “P S” but is not. Both characters joint together (제조) are translated as “Manufacture”.
