Let's be realistic: it is a Poor condition revolver.According to Standard Catalog of S&W 4th Edition.
...based on the 2 screws in the left side plate, grips, ribbed barrel, round blade front sight and the knurled barrel latch...should be 5 shot cylinder.
I say it's a .32 Safety Hammerless 3rd Model, produced from 1909-1937.
Serial range roughly from 170000 to 242981.
Value estimate based on the condition shown (you decide):
Poor $80
Fair $150
Good $200
VG $250
That's just the really long (for the Lemon Squeezer's chambers) .357 case bottoming out on the short-short .38 S&W cylinder (same ridge you can see looking into your .357 cylinder).Then I opened it and dropped the round into the cylinder. It went in until it hit some kind of ridge with a clunking sound. Does that mean this revolver has been fired so many times its barrel and cylinder are way out of spec to the point of being unsafe to shoot?
