The single action top breaks were an interesting part of Smith & Wesson history. I wanted one in each of the calibers shown here. Took a while to find. They are: 1) New Model No. 3 Top Break SA .44 Russian 2) SA Top Break .38 S & W Second Issue 3) Model 1-1/2 SA Top Break .32 S & W. All are in excellent condition - the .38 seemed unfired - and all of them shoot.
