Hi to all. I have a question regarding a Colt Python I own. It is a mint condition 1976, royal blue, 4 inch barrell. I have the original box with serial number but the cardboard part of the box is not in great shape, the inner styrofoam and booklets are. This gun has in all probability never been fired other than factory test firing. I dont want to sell the gun but I would like to trade it for an electric guitar of similar value. Therefore, what would be the approximate value for this piece? Thanks for your help in advance.
