Going by the pics, which are numerous, but not great, I'd say it's a nice, but fairly run of the mill M96, which would typically go for about $350 (the scarce rear sight adds about $50 to its value).
However, as mentionned, the bolt is not right, and it does not appear to be as simple as having a M38 bolt - it looks like someone bent it. If the stock has not been damaged, you could look for an unbent M96 bolt (not easy to find and go for $50-100), and sell it as mismatched in the $250 range.
