One can blow up the pictures already posted and the jeweled Pre' 64 extractor can be seen.
I do think some careful work with emery cloth can "un-jewel" much of bolt, if someone was of a mind to.
ChanceD, I don't know the market well, but if the length of pull is not too short (looks OK in the pics?) and if the rifle is accurate, then I think you made a hellofva deal for $600!
