Does anyone know how to date a S&W gun or is there a site i'm missing that could help me? I'm looking at a S&W 4006TSW and wanted to see when it was made and then find out what they are going for. Thanks for any help.
There's gotta be a S&W forum out there, with members who know the answer you seek.
I know that there are books available, with published data of the kind you want. But no, I can't recommend any.
Maybe try Jim Supica's Standard Catalog of Smith and Wesson, last published in 2007 (I think).
