Now it seems to some degree that you cannot even trust the Colt letter. A 3" nickel Python popped up on gun broker today New inbox with the Colt archive letter. The problem is that I have that same letter from the gun showing it as a 6 inch blue. I lettered it two years ago when it was on a penny auction so I could authenticated in order to bid. Of course with what the letter said I did not. I contacted the seller and sent him a picture of the genuine letter. He was shocked to say the least as he bought the gun from a person that keeps popping up in discussions about boxes. This letter was really good seal and all. He immediately canceled the auction and I will not link it to protect his identity. I will be contacting the Colt archive department as this is blatant fraud. I just wanted to post this so everyone is on the lookout.
