Thanks, David. Francis has had some health issues, and I haven't heard from him in awhile, but wish I could. I spoke with his wife last year, at some point, and she shared that he was getting better but still struggling.
I know that this is the second set of barrels the gun had, as Francis still has the first set. He had them fitted to another Smith gun, that he shot for a long time. He told me once that if he ever decided to get rid of the gun I could buy it. It'd be nice to put the original barrels back with the gun.
BTW, the original owner C. J. Backstran (whose name is etched, or lightly engraved, on the right barrel) was a pigeon shooter at the old Philadelphia Gun club. We speculate he had this set of barrels, with the 3" chambers, made for pigeons. They are certainly choked for the game.
