Would like to know the origine (maker/country) and year of this case and/or explanation of the headstamp. No ink marks on case.
Thanks.

Headstamp looks Russian so can be for tank, anti-tank or navy. Rim should be 112mm diameter. Nice case.
This case also used by Poland and Czechs. My reference is Hawkinson's book "Big Bore Ammunition".

Hi Ron, I've got also that "Russian"-feeling. Rim is 112mm. What I found till now, is that it's been used for D44, T34-85 guns... I hope that someone can explain the headstamp/maker/year...

I am unsure of ID but I have 187 listed as Novaya Zarya Plant, Tula. I leave it to the experts.

Apparently also used in a Russian anti-aircraft gun 85mm M1939 (52-K).
