Is there a book that can be purchased that gives details such as year of manufacter by serial #, or range of years by other descriptors (-3, heavy barrel, etc.). Thanks for the assistance.

Standard Catalog of Smith & Wesson. You can find it on line cheaper, or go to a book store like Barnes & Nobles.

This is the best resource. Please keep in mind that if you purchase it, I'm not responsible for what happens after that, especially if you have a GunBroker account. Oh, "warning" never mix GB, SCSW & any form of alcohol.

Welcome aboard! You are already in the best place to ask questions.
