That about brings you up to WW II
Mexican Model from just after the war...still had the long action...
Then there would be the modern Speed Hammer action in the Post War Transitionals when S&W was abandoning the War effort and retooling...
I'd have to look in the "books" just to make sure none have been missed but they got 'em listed above pretty good,( nice picture ****..) then after WWII...the K-22 Target and Combat Masterpiece, the 22/32 Kits guns "again" ( still...)......... the Model 17, model 18 and the models 41 and 46, and Escort mdl 61 semi autos.......... hipnp
( yes, the "kit guns" were models 34 blue, and 63 ,stainless...)
Looks like a pretty comprehensive roundup, justj, but you might want to pick up a copy of Standard Caralogue of Smith and Wesson, 3d edition, online or at your local big box bookstore. That way you can really read in detail about each and every variation of each and every model.
