The 22LR was never a "production" model.
For some finding one of those guns in 30 carbine would be one of the S&W holy grails, I believe I read that the factory did several of those. There is also the custom wildcat 357 Bain and Davis, a 44 necked to 357.
I "think" the factory list is
22lr???
30 carbine
9mm
38 special
38/40

What did I miss
My N frames are 45 ACP and Long Colt, I love all 6 of them.Most of my N-frames are chambered for 357 Magnum, 10MM Magnum, 41 Magnum or 45 Long Colt. The 44s do not particularly appeal to me, though I do own a few.
If you are trying to get a modern N-frame in each caliber, you are missing 22LR, 9MM Parrabellum, 38 Super, 10MM Auto, 45ACP and 45 Long Colt. Possibly others that I can not recall at the moment
