This group includes .38/32 RP Targets and the 196 .32 Reg. Police Target 'I' frames, a 1957 release non Model #'d with pre war sights numbered to the gun, small trigger guard and leaf mainspring (pre Improved 'I' frame), (Shown 3rd from top on right), made on left over pre war target 'I' frames. Th is model still has the smaller pre war cylinder diameter and frame window. Frame serial# stamped on front grip strap above the strain screw matching all other #'d parts inc. stocks and sights, 8 locations in all, (in low #657XXX range). 4" barrel, pre war/early postwar rebated rear grip strap, sq butt stocks, with post war type 16 lpi checkering, round cornered border on round top stocks with curved nickel plated brass medallions. You'll notice pre war sights supplied w/ special modified pre/post war blue all steel sight adjusting tool (SAT) to fit tiny sight screws, pre war/early post war hammer, post war grooved trigger, and 3rd type post war (and post 1966 aft er becoming J frames) non-sculpted thumbpiece while all other I frames of the period still had the third type flat latch. Most features are inconsistent with non-target pre Model 31 guns of the 1957 period! Including the 3rd post war style straight ejector knob (left hand thread), 4 line address and no patent dates on barrel. A very convoluted transition model for sure. Brief details of these 196 guns are on page 128, 3rd edition, Standard Catalog of S&W, Supica and Nahas, pictured pg 127.
