Stocks of Smith & Wesson

 Smith & Wesson put out a variety of stocks and it takes a keen eye to be able to distinguish them.  I have seen amazing copies come out of Thailand and other parts of the world that are almost impossible to distinguish the fake from the originals.  Companies have done their homework when it comes to replicating the original stocks.  A really nice pair of original stocks will sell for around $100 on eBay and buy it now prices are always around $150.  You can however purchase them on Midwayusa's website that are OEM.
The best source for locating pictures for the different types of grips would be some of the Smith and Wesson Forum groups, the S&W catalogue, and collectors.  There are several different ones all over the internet and the members are filled with S&W facts and photos.
Essentially we are looking at several different types of grips on many different frames.  To know them all is a stretch and they had some rare ones that even the best historians can't identify.
