Yes - Jim Supica and Richard Nahas Standard Catalog of Smith & Wesson, 3d Edition, Gun Digest Books, available through multiple online sources is an extremely handy reference to have around if you collect Smith's. Along with the above mentioned serial number charts the illustrations, most in color, are excellent, as is the background and info given on the models. The SCSW has made if clear to me what type stocks (grips) should be on a given revolver, how old it is (think C&R) and how rare it is. When purchasing collectable Smith's it really helps, but it also, I fear, strongly encourages mine and a lot of others addiction to buy these things - they are just so darn interesting.
