I have two 1970 Bally target zeros looking to sell. One appears complete. I have looked it over and see nothing missing. The other is missing a few items off of the front door ( counter, relays and timer board. I have not dragged them out of the storage locker to put power to them yet but other then being huge it looks like the one would work. The playfields are in both but since they are vinyl / pvc they have curled on the sides and a little brittle. I was just going to get some white vinyl and replicate and repaint the playfield and sponge buildings on it. I will get some pictures shortly.
