I have some time and the energy to try a total restore. I am taking an old machine and try to make it look like a museum-quality piece or hopefully at least just came off the factory. This means playfield repair/repaint, cabinet repair/repaint, all mechanicals removed and polished or restored. It is an oldie, 1965, back in the day when it didn't even shoot out the ball, you had to push a lever to bring the ball up into play, but that also makes it a bit simpler to debug if I screw something up terribly. It will probably take me 6 months or so but I am retired and it keeps me out of my wifes hair!
Here are a few pics of the original - which has a couple of sticky coils but otherwise played perfectly.
One thing that is really cool, is the posts are shiny metal! not a plastic. This seems like a golden opportunity for someone to make new chrome posts.. they would look awesome!
