John,
I noticed in your playfield (after Restoration) photos that the holes for the flippers hadn't been changed back to original, did that cross your mind (repairing them) to keep it original? I think you mentioned somewhere that ops were told to drill them out to lower ball times. I also notice that you have amber bumper caps ready to install, was that the proto colour?
I have a soft spot for this machine so I am really enjoying your restoration.
