Only after 1950, and even if it was, the lack of other accompanying marks make it unlikely in the extreme that it's Russian in origin. I don't see any Russian proof marks on this gun.
The mark for full choke could very well be post 1950 and I can't dispute that because I just haven't seen that many examples. Early on, pre-WWI, Russia's proof methods didn't have any rigid structure. We have an example and the mark has to fall in one category or another. I can't tell but beside the "Trade Mark" stamp on the underside of both tubes of johnmwmd's pics post, there looks to be some Cyrillic, or the like. Then again it could just by my eyes.
By the way, what are the chokes, measurements on this bird??
Pretty neat, Geno, how you edited the pic. Can you edit the pic of the tubes with the letters beside "Trade Mark" for me?
Kind Regards,
