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.
