I've seen a whole bunch of them over here. They did make a few quite nice guns during the socialism era, by the way. There is a sure way to tell - the Pre-Revolution guns will have the two-headed eagle stamps over the barrels, and the "Императорский Тульский Петра Великого Оружейный Завод" inscription (in the pre-1917 orthography I can't imitate here) on the rib. Unless it is one of the bespoke guns made before the introduction of Model B, in which case it is even more rare. A few pictures sure wouldn't hurt.
