First I suppose you are talking about a Parker. So what would the gun be worth if everything was correct and in the same condition. Then compare it to his asking price. Is he already discounting the fact that it's been re-stocked? Asking prices are "starting" prices. Everything is negotiable.
Then you must decide if you are willing to pay more and be able to accept it as it is. If it's going to be your shooter and it is a reasonable price then buy it. Evidently it got something to get you this far.
