The Standard Catalog of Smith & Wesson
I see another responder has Pointed out an excellent source of S&W serial numbers
and it will provide many hours of good reading
on all the different models they made and make. The Only True way
to know when your gun was shipped
from the factory is to apply for a Factory letter.
Some models are not as fast selling as others and although a reference book shows serial numbers and list's years when they shipped, it can only be considered a general idea
of that model as I have seen some that shipped several years
after these books show them to due to a less Popular status or demand for them. Here is a direct link to the Factory letter
I spoke of and the Excellent reference book
the Poster before me mentions that can be ordered from your computer and shipped to your front door. Another excellent book written by the factory Historion Roy Jinks is also shown and I have it as well and I highly suggest it as a Great choice.I hope this helps, Hammer It
