Oh, and thanks for the tip about them! I didn't know about the numbers. The ones on the bolt and reciever are the only ones there so I thought they were original. The original no. on the magazine floor plate has been crossed out and replaced with the reciever/bolt #, so I thought it was all that had been replaced. The stock is a later model post war replacement, according to the site. I'm happy either way, and just ordered another one.Great condition! Wow.
Numbers were forced match when they refurbed them after the war. Look here for more info than you'll ever want to know about these old rifles: http://7.62x54r.net
