I have a 1964 Williams Zig Zag. I've had it for a little over a year now. Craigslist find. I had been looking for this machine for a couple of years and finally found it. I have repaired everything that I can and it plays great. I'm missing two parts and looking for advice where to best locate them. The primary tilt plum bob is missing, including the contact ring. Also missing is the knocker device. Any help on where to locate these would be most helpful. Another question is the match score. When the game over last digit matches, you can tell because the machine has a very slight and brief dim of the lights, but the credit score wheel does not advance. It could have something to do with the missing knocker coil, but unlikely, as the point scores do advance the credit wheel. Thanks for any help or advice you may have. Regards.

Thanks boilerman. Ordered today!

As I was installing the new tilt switch, I found this photo on the ipdb.org site for reference. I see that I am also missing the ball tilt device too.

But more interesting to me is in the photos. Can someone tell me what the legend at arrow #1 says? Also the selector wire shown at arrow #2, what it is and where does it go? You can see in my photo, I'm missing the legend and the wire plugged in.
