[quote=“DocAV”]Firstly, is it Russian/Soviet in origin?
It could be a 7,5 Swedish Nagant, or a 7,5 Swiss Nagant. all very similar types.
The lack of headstamp could be Soviet wartime production, or just a case which “missed” being headstamped.
The Powder looks very “Germanic” or “Polish” to me.
A close comparison with a known Soviet Cartridge to note manufacturing similarities and differences would be of help.
As per my experience - this cartridge don’t look like Russia/Soviet made. Russian Nagant cases always has flat primer and very small bevel at the rim. Most often they have 2 center marks to fix the bullet. The bullet could have cupronickel or GMCS envelope. This sample has very “bright” colour of envelope, which looks like nickel plated. Also case mouth didn’t typical for Russia - it has a step, instead of Soviet conical reduction. Only powder is similar to Soviet smokeless pistol powder R (Pl 10-10).
On Monday I will show a comparison pictures with Soviet cartridges and this specimen.
I think that this cartridge could have scandinavian origin.
