Ok guys maybe I can get a answer here or someone can point me in the right direction (other than Factory letter). I recently found a Colt SAA 1st gen. serial number 317xxx, I have done some reading in the blue book and everything matches to a “T” even the Colt rampart circle is only half there, the book says the reason is that colt's die stamp was almost wore out. My question is on the side of the trigger guard there is ,if I remember right, what seems to be a small V stamped almost like a proof mark . I am unable to find anything on this and colt wants almost 150 bucks for a letter, the blue book of gun values won't answer any questions until you have obtained this. If I get really serious about buying the gun I will request a factory letter prior. I just want to find a little info before I sink my $’s into it. Thanks jmw00
