Hello I have a S&W .32 cal long revolver 4 inch barrel from my dad it may have been his dad's. I think it is a police model the # I found when I took off plastic grips is 516_ _ . I see not everyone uses full serial number, the same numbers are on the back of the cylinder. The last date stamped on top of barrel is July 1903. I would say fair shape at the most. Most of the finishing is off, was wondering the value.
