Can anyone tell me approximately what year Colt had a "Q" for a serial number suffix with their Colt Frontier Scouts in .22 cal? I'd also like to know a ballpark value as well. It has a 4 3/4 inch barrel with the original black Colt plastic grips with very little scratches over all. It also has an aluminum alloy frame, black cylinder & barrel. No magnet sticks to frame.
