Mark Twain on the S&W .22 (Model 1):
" I was armed to the teeth with a pitiful little Smith & Wesson's seven-shooter, which carried a ball like a homoeopathic pill, and it took the whole seven to make a dose for an adult. But I thought it was grand. It appeared to me to be a dangerous weapon. It only had one fault--you could not hit anything with it.
One of our "conductors" practiced awhile on a cow with it, and as long as she stood still and behaved herself she was safe; but as soon as she went to moving about, and he got to shooting at other things, she came to grief."
Comment: I have a few of them tucked away, too, but never got up the nerve to fire any one of them. I suppose with a .22 short (is it CB cap ?) it would be fine but you're solely on your own, at your own risk. Have it checked over by a qualified gunsmith who is familiar with these oldies... before you try shooting it, I suggest.
