Ebjonnes. Rebuilding the K-22 to 3-3 1/2 inch gun kinda reminds me of a story told by a local car collector/restorer. An individual showed up at his place of business one day, and after some looking bought a vintage 1929 (totally restored) Ford Coupe. A short while later the same individual showed up again bragging on his new T-Bucket. He had taken the vintage car, cut it up, installed a big block Chevy engine, corvette drive train, and disk brakes all around. Not only had he destroyed a vintage car, he had spent far too much money to do it.
My friend said he had 5-6 frames and body's that he would have sold the guy for about $200. A good start for a T-bucket. But this nut paid $10,000 for the car, and (guessing) near that amount again to convert the vintage into a T-bucket. Had he bought the frame and body, he could have built the car for about a quarter of what he had in it, and of course, the vintage car was gone forever.
Ebjonnes. If I were in desperate need for a short barreled .22 I would look around and find a used gun that was in need of restoration and work with that rather than butchering a vintage gun. JMHO.
