22LR 4" 3 screw pinned barrel question
I'm looking for a model number for this 4" S&W 22LR revolver. It is in dirty condition and I've made no attempt to clean it at this point. Serial number is 307XX and as you can see the only other numbers are under the yoke. I would like to know the model number and the production period and whatever other information someone may have. Thank you!
