Lately I have had a interest in older revolvers. I recently came across these two J frames. The stainless revolver is the model 60 and the blued is the model 36. Other than material differences I believe they are the same revolver. Smith began manufacturing of the Model 36 in the 50's and the model 60 in the mid 60's. According to a little google search, the Model 60 is supposedly the first regular production gun to be manufactured in stainless.
