Shortened .22 Super Single Six
Modifications:
Cut the barrel: mathematically 4 7/16" is equal to the proportion of the mid frame with a 4 5/8" barrel. But that would need a cut right thru the ERH screw. So I resorted to 4 1/8".
Also pulled the barrel and turned it ¼ turn so the rollmark is on the side to match the OM Blackhawk FT. This had two more advantages: it keeps the relocated front sight from covering the rollmark and it allowed me to clean up the course machine tool marks on the front face of the frame so typical on OM Rugers. That in turn allowed the extra ¼ turn of the barrel after cutting the barrel from the front end.

Flattopped the frame to match my old model mid frames.
