A buddy of mine has a gun purportedly to have been owned by Bill Tilghman. I looked at it yesterday and it looks like the real deal. Its a Colt SAA. He is waiting on a factory letter and he already has pretty good provenance. A few years ago, on the old format forum, I put out a help request. I was doing research on an Oklahoma Territorial marshal's gun. A member here put me in contact with a guy in Alabama ( I think) who was a Colt SAA expert. I don't remember what member it was, I think his real life name was D. Alan. If any of this rings a bell, please PM me. I plan on letting the owner of the gun get in touch with the Colt expert. Thanks guys!!
