I assume it's a Military and Police, fourth series, so probably made in the early 1940s, based on the serial number. Bueing is thin, but most is still there, and there are a few superficial rust spots here and there, but it appears functionally perfect. Bore is bright and shiny, rifling sharp. Cylinders are bright and shiny too, other than the dark area past where the cases go. Looking forward to shooting it. Paid $210 out the door for it, so not a huge investment for a nice gun with character that you can actually shoot and keep loaded for defense. Action is smooth as glass, and single action is your typical Smith & Wesson crisp light break. Serial number is S 9485XX. Anything you revolver experts can tell me about it?
