I don't know much about them myself but this one is a mix master with at least three different serial numbers although it looks like the bolt all matches itself. It does not look like a Russianicon capture, no "X" or "crossed rifles" and it doesn't look to have been refinished. Looks to be in decent shape but it has some rust I'd try to get off before it causes significant damage. What's the bore like is the big question most will be curious about.
