Manufactured in 1920 and later Colt factory rebarreled and rechambered for the .357 caliber cartridge. The barrel has the one-line Hartford address on top and "COLT SINGLE ACTION ARMY .357" on the left side. The left side of the frame has the three-line, three-date marking followed by a Rampant Colt. Matching numbers on the frame and grip straps. The trigger guard has the number "3", Colt factory triangle proof and 6-pointed star Colt factory rework mark. Fitted with checkered Rampant Colts with the back of the right panel hand marked "JOHN W DAMON/COLUMBIA TEXAS".

Fine as Colt factory rebarreled and rechambered (see above). The revolver retains 70% original blue finish (mostly on the barrel and cylinder) with the balance a smooth gray patina. The hammer retains bright and vivid original case colors and the frame retains traces of original case colors. The oversize replacement grips are fine with a few small notches near the bottom, a small chip missing near the bottom and overall crisp checkering.
