An original model 1860 army model, given in trade to my father by the son of the original purchaser for gunsmithing services performed.
The old timer who gave it to my father wore it daily while working his cattle ranch back in the early 1900s in the Mohave area of Calif. Horse spooked one day and threw him off. When he picked himself up off the ground and started gathering himself and dusting himself off, he realized that the Colt was no longer in his holster. Gettin' late, he left it there and started after his horse. Came back the next day and try as he might, couldn't find it. Came back to the spot many times over the course of a couple of months and couldn't find it. Gave up and bought a replacement pistol. A month later he was near that spot and decided to stop, take a look and eat lunch. Sat down on a rock to eat a snack and saw a glint of sun reflecting off something under the edge of a largish rock where a bush had grown up against the rock. Yep, it was the cap n ball revolver. Except for the last 3 or 4 of inches of the barrel, it wasn't too badly rusted. He took the grips off, dunked the rest of it in a bucket of oil, wrapped it in a rag and stowed it away in a trunk where it stayed for over 20 years.
Dad cut about 3 inches off the barrel that was too rusted to save, turning it into a somewhat abbreviated Sheriff's model. Birdseye maple grips.
