You all seem pretty informed. I recently obtained a Smith & Wesson 32 Double Action, tip up revolver (1880 to 1919). It is nickel finish with Mother of Pearl grips (grips have brass S&W logos). The seriel number is 2318XX. This is the only S&W I own and if I'm going to spend $35 to buy the book, I'd rather spend $30 to get the Letter of Authenticity from S&W. But first I would like to know which century it was made in. Any volunteers willing to help.
