Hard to see Rune, because of X. Looks funny. What’s the full serial?
Not sure as the other photos aren't very detailed.
OK. May or may not be a single rune. If serial has a letter block it definitely is not a single rune. If it does not have a letter block then it is possibly one, but that rune is masked by the X. That would be a red flag to me and I would not buy it. It could be a no letter block BNZ someone faked. BNZ is not my specialty, so I would not buy for the reasons I have mentioned. Some guys here specialize in these and I'm sure can add more info. Russian captures never really excited me either. Save your money for a bolt mis-match.
Even if it is a fake, its a good price for a Russian capture so i'll still buy it. Not really into matching 98k's anyway, too expensive lol
I guess when your new it does not really matter. I would not pay much. When you go to sell it make it hard to explain away issues. It sounds like you made up your mind before you ask. I hope it works out for you.
