Once again the 22 bug has bit me. They've been coming out of the woodwork this month. First a 6", Ruger Standard, then a High-Standard Sentinel, and yesterday this one. Ruger Standard Auto, (sometimes called a MK I) 4" barrel, from 1974. I'm not sure what I'll do with it, but it can be trade bait anyway. A couple of scratches and dings, but not too bad I don't think.
