I recently bought out the parts inventory of a deceased gunsmith who was
heavy into S&Ws. In the bottom of a box, I came upon what I can only call a single shot adapter. It replaces the whole cylinder/crane assy, swings in and out, ejects, ect. just like a cylinder, but only has a single chamber. I'm trying to figure out if it's a factory part, and
why someone would use one. I'll get some pics and post them if needed.
