I have recently acquired an .22 Officers Model third issue and I am having trouble re-installing the crane back into the frame after unscrewing it and pulling it out for a clean. I line up a flute on the cylinder with the crane so it doesn't grind into the frame, but no matter how I turn and twist and push I just can't get it to snap back into the slot fully. I did once before, but it seemed almost by accident that it happened. Is there a technique I'm missing, or is it just a matter of trial and error? Thanks for any advice!
