9/24/19 - Inspired by the success of the Colt Python, the Diamondback was manufactured and released beginning in 1966, and resembles a scaled-down version of the Python. This particular revolver was made in 1978, and is chambered in the less common .22LR with four inch barrel. The gun is in mint, original condition with only a faint roll mark on the cylinder. The gun is accompanied by the original, matching box, complete with Styrofoam sleeve and original manual.
