Have an opportunity to get a colt snake gun I've always wanted and have a few questions about the value and want some of you guys to give me some input on it. It's a king cobra in 357 supposedly never fired but it's missing the box/documents and original grips. How much is the value decreased without these originals and what would you guys estimate it's value at? Will try to get more pictures. Right now this is the only one I've got. Thanks for any input yall can give me
