I picked up a nice nickel 19-4 2 1/2" a couple of months back, but am struggling with wanting to shoot it and also wanting to preserve it for posterity.
I had an issue with a phony box with the 19, it became the subject of a thread on here at the time. It was resolved and I got the gun at a good price, but it has now put me on a bit of a mini-crusade against phony or non-matching boxes. I'm no expert on this stuff, but am doing my utmost to educate myself. When I spot an obvious but not admitted mis-match between gun and box I'm going to call it out. There is no reason for it other than to scam someone, pure greed and deception, no nice way of putting it in my humble opinion.
I totally agree with you. I would suggest you be wary of the Colt forum as fake boxes, hang tags, papers, etc are as rampant there as the little horse.
