About 6 or 7 years ago my wife gave me a Python for Christmas. My brother, who owns a pawn shop, got it for her. It is a beautiful piece. I fired about a box of .357s through it, cleaned it, and put it in the safe. Since then, it has been removed for cleaning and admiring. I had assumed, since it was a used gun, that it was nickel. It was in a plastic colt box that appears to be made for up to a six inch revolver. (mine has a 4" bbl.) The finish appeared to be identical to a Diamondback I owned briefly about 30 years ago. Now I am beginning to wonder if it might be stainless and not as old as I first suspected. The serial number is V848XX. Any info appreciated.
