As the thread is revolvers only,
If we skip varients of the Model 60 such as the 60LS and 60 LS357,
Staying in rough order would require models , 63, 65, 65LS.
66,67, 68, Then C frame M73, then triple digits beginning with the 242.
I believe someone posted a 4" Model 66 earlier but the Model 67 was not,
Here is a 2.5" Model 66 and a Model 67 together to keep it moving.
