Here is my problem. If you don't trust the individual, or better you don't know the individual, how can you be sure that the label on the paper box wasn't bought on e___, or that the tools or paperwork weren't bought there as well? You can ask all the questions that you want, but if you don't know the individual, or have some way of checking their background, then how do you know what is real and what isn't. I have seen guns advertised as having all the items that would have been part of the sale, and the case looks about worn out, and the gun looked pristine. How does a presentation case get worn out, while the gun stays nice? I don't have the funds to do a lot of "high end" collecting. I try as much as someone with a limited knowledge of what was made when, to buy authentic when I do buy a complete S&W revolver. I am always a little nervous until it is in hand. I just bought a 629-1 from a forum member as a shooter. It is as tight as a new one, but has been shot and shows a little handling, but you know what? It was one of the most relaxed, enjoyable S&W purchases in quite a while, and I look forward to giving it a spin asap!
