Got these in the mail yesterday. Think the 29 is my new favorite. Love the cokes. The pre 19 is really interesting, everything numbers including the blued barrel. There’s no N on the barrel so I don’t think it was originally nickeled and blued over. It does have the diamond and the B. Might letter it but if it was an aftermarket order wouldn’t do much good. Wish I knew who owned it. Big thanks to Mr. Newell who I got the guns from. Great to do business with.
