I purchased this Colt Lawman MK lll quite a while ago, from the woman who purchased it new in 1978. I have been trying to find an approximate, current value of this beautiful revolver, I've checked here on NWFA and on gunbroker without much luck. Can anyone on here give me an idea of what this may currently be worth? It has been fired, and it has a ding in the left side grip, as shown in this picture. Any help would be greatly appreciated. Thanks
