I know that the gun does not have the last patent date that was added and has type 1 rubber grips (the original design before it changed). The sample in Combat Handgun had type 2 grips with serial number of 295***. My Pistol is 102***. It was my grandads but I dont know where he got it from and has been deceased since 1995. Unfortunately it was not taken care of very well and has some significant rust but nothing that interferes with the function of the pistol. I have been thinking about calling Colt and seeing if they would restore it for me, but am afraid to affect what value it may have and also dont want anyone knowing that I actually have it (know what im sayin??). Got any opinions on what I should do?
