Seriously though did the range dial actually work? Do you actually set the distance with the dial while looking thru the eyepiece and then push the button for either he shell or ap shell? Or were those buttons used to tell the auto loader what to load and then a button on the yoke was pushed to actually fire the round?
And last question, how hard would it be to make a working clone of the cabinet? Not an accurate internal clone but just one that worked in the same manner as I suspect a lot of the internals are special one off items...
