There are only a few Gottliebs that I haven't played starting with the metal rail era. My brother keeps track of such things, and says he has played every domestic Gottlieb wedgehead. The last one he played which completed the series was "Road Race". For some reason, it took a while to come across one of them. I've probably played just about every Bally multi-player game, but not so many of the elusive single-player titles from the sixties.
Probably have played most Williams metal rail games as well, but I don't think I've ever played a "4 Roses".

Is Tom and his fantastic collection still around? I haven't heard anything from him or about him in a loooong time.

Well, according to my brother's count, he has played 557 different EM pinball machines including 284 Gottliebs. As I said, he keeps track of such things. Back in the '70s, I used to keep a log of all the games I saw at each location. If we went back to a place and a game was gone, it was put in parentheses. I still have that book. There were many locations back then that had EM pins, most had several. We helped run an arcade for a couple of weeks one summer. As I recall, almost no one showed up to play during that whole time! We had the keys to all the games, and it was great to have our way with them. Those were the days!

One of the best pins ever. You'll love "North Star" if it's playing correctly.

Thanks. I haven't been out to the left coast in a few years, and unfortunately my base of employment is no longer out there.
