It appeared to be on some type of inventory sheet that included serial numbers when I went to pay for it. I did not see any scrabbling to rectify any numbers. Numbers on the gun and box match, all things I have thought about. Nothing during the transfer appeared to set off any alarms about something being wrong or out of usual. Again I have bought a lot of used guns, and I check condition of used guns with much more diligence. Just wish I would have looked at this one more closely. I don't care about the lint, I'm most shocked that once it was cleaned there was so much cylinder play. Not a gun I would have accepted on the used market.
