Bravo!
I have 2"ers and 4"ers. One Model 1953 I frame like yours was reblued, nice job but not factory so when I saw a 3 1/2" Airweight barrel (they're not marked Airweight) for sale, I grabbed it. Just to have something different and put it in my I frame.
I had a pre war style barrel knob ext rod from early post war with left hand threads so I notched the 3 1/2" barrel and installed the rod too.
It's my favorite .22 shooter.
