hi, know you give me some information on this case. I can read in sequence: 35. P. S. 14
You can try brushing the headstamp with an old toothbrush for easier reading. I’m sure it won’t devalue a fired cartridge.
It looks like “P S* 14 35”, P is likely to be Polte, and the round is probably German from 1935. May we see the whole thing? S* likely means “brass”.
