Confirmed by the included Colt factory letter this prototype Python revolver was kept by the Colt factory as a sample of electroless nickel finish. The letter also confirms the caliber, 6" barrel with standard markings, electroless nickel finish with blue finished cylinder and sights, and without stocks. The left side of the frame has the Rampant Colt. With pinned blade front and adjustable rear sights, serrated trigger, and checkered wide hammer spur. Complete with a maroon Colt "Heritage of Craftsmanship" box with Custom Shop end label numbered to the gun. Provenance: Colt Factory Archive Collection.

Excellent. The revolver retains over 99% of the respective finishes with a few minor scratches and a noticeable cylinder drag line. The box is very fine.
