Not to be a negative-nelly, but I'd be rather surprised if you got that for it. I suspect it'll be hard to prove the markings are original and so you'll get closer to the $200 or so most M95s are selling for...that said you never know, you might get lucky like RCArms.com and find a buyer that can't live without it. I think you'd want to be careful though about selling it as a true Nazi marked rifle unless you were sure it was authentic. You wouldn't want a buyer to try to accuse of cheating them/making the changes yourself (even though the marks predate your ownership, they may not know that or assume you did yourself).
