got a couple, they aren't terribly uncommon... since I shoot mine I put more value on the center fire models, since I can reload, & there is still factory ammo available... the snubbie is worth a premium, as 3.5 - 4" barrels were the norm... Blued guns in this era are worth more than the nickel ones, grips should be hard rubber ( careful as they get very brittle, & they often crack around the pin, when removing )
my best guess without pics as to actual condition, would be between $100.00 - $250.00
here are a few to look at on Gun Broker... ( as you can see, I think all pictured are 32 S&W, so are you sure yours is rimfire ??? )
