Thanks for the confirmation. It was, what I supsected.

I looked at gunbroker after I wrote my post and I see that people do not bid on ones like mine or not often, so to sell it is not likely, but I do not like this strange hunting rifle cut-off.

So I think, instead to sell it, that I will try to restore it with correct barrel and stock length (either replace entire stock or front part). I have read that someone did this, and will still cost less than new one because rifle was free to me.
