The finish of the stock looks too good to be the product of a soviet post war refurbishment and this would suggest to me that the stock, at least, has been refinished somewhere other than Russiaicon. The stock may have been refinished by a private owner after becoming a milserp piece and so could could still be a Russian refurb or it could be the the the finish applied by another country doing the refurb such as Poland. Can you see any boxes with number "11" which are often seen on Polish weapons?
