Today i bought these 2 57mm Shell cases from the local flea market.
The casing made from brass have a wood shell, the other one have a cyrillic writing on the body of the case.
The marking from the brass made case
The marking from the cyrillic writing shell case
As far as i know, the S60 used extensively by the TNI from the 1960's until today.
Although some already retired though
So is there anyone can help me determining how old these cases is? From what year these 57mm was made?
