Hello All. I have been given a 380 revolver mk 2 round, with the head stamp C|S .380 2Z GC It came from a box with a 1974 date on it. Does anyone know what the C|S means ( country, factory etc) As the packaging was military I'm assuming the GC means government contract. The only reference I have is from an English translation of 'Manual of pistol and revolver cartridges' but it does not give any details! very irritating :tinysmile_angry_t: I hope someone can help.
