Quoted from TomN:Interesting, but I don’t think I would like to own a prototype of any table. My ocd would get the better of me if I had to look at wrong inserts or other small things that had been changed. Anyone else feel this way? If I were collecting for only financial reasons then maybe. I collect to play and for little projects here and there.
when I was hunting for a tz, I actually found and bought 2. one was a proto. I would have kept it, but someone had put the wrong screw in the flipper bracket and the top of the screw pierced the top of the playfield. It was pretty minor and I think it was behind the flipper rubber. but given the choice, I kept the better condition production one. Probably was the wrong choice.
I dont remember if I checked or not, but I dont think it had the 3rd magnet. It did have a white clock. This was back when tz was about 2 years old. I sold the proto to a lady in LA area. She had a very nice and large collection. I might have pics of it on my computer, but I dont think I took a pic of the serial number.
