First timer here. I recently acquired a very old what appears to be a Walker-Colt 1847. On the butt frame I can barely make out a single 2 as on the barrel underside panel near the trigger guard. The bore rifling is very worn and the cylinder shows signs of scorching, typical of overloading and spillage. The cylinder has very deep etchings and W.L. Urmsby Sc. NY. 9” barrel and 15” overall. Lots of pitting but operates beautifully. It had some rusting overall but better after using some light museum wax. Lots of old black powder residue. The number 564 appears on the burned side of the cylinder. There is so much black scarring on the underside as to almost obliterate any other numbers. It does appear the top of the barrel was worn and shows no address or it could be a replacement. Weight about 4.5 lbs. The cylinder appears to have some white/ silver color. This appears to be a well used piece. I have dozens of detailed photos. I’m wondering if this could be a true Walker-Colt. Any thoughts.
