You've been real creative in using 392 parts on the HB. Strange how we both came up with the concept of using a HB-22 as a survival gun. I stored all the parts required for resealing the HB, an Alen wrench plus a few other small parts in the grip frame between the two grip. The roll pin and screws have been changed, so only a screwdriver and Alen wrench is required to disassemble it.
I may have taken my HB over board with the Rick grips and the gold inlay. I call it the "Survive in Style" model.
