30x210B Questions


#1

Hi, gents!
I have a fired case from a soviet naval AAA cartridge 30x210B. Wish to ask about the year and place of manufacture, as well as for the meaning of headstamp numbers and symbols. It is 12 o’clock: “52-78;” 3 o’clock: “K”; 6 o’clock: “184-И”.
Thank you in advance!

Ivo

Thank you very much! I suppose the number of this plant was 184. And what about the other symbols - “K”, “И”? Is “52” a lot number or what?

Cheers!
Ivo
