Re: Bolt SN:
I have one I purchased from a trusted fire member. If the rifle was used, it was less than a little. The bolt SN is there, but you have to look hard for it.
Dad bought me my first back in perhaps 1960. A friend of the family worked for Winchester and when the stock cracked he took it back to have it replaced. It came back with a new stock and the bolt jeweled. Never prove that one today to a collector or Rule. "No, can't be." Yea, it could.
