it ran from a gas engine, and had very little lights (by design, not elimination). The monkey-heads on the ride HEAVILY resemble the Herschel design used on their Carousels from about the same period, with only slight differences. I can't remember much more about the ride, but maybe that will be enough to tell just what it was.
If it looked like an AH piece then it probably was. Sounds like the looper.
The other 2 were definitely Chance.
The design element in the W'Wheeler I was referring to was the introduction of a CPU to rides. That was a major move but didn't go over so well. You had to call in an expensive tech whenever the system crashed. I thought the tubs were homely and suited for kids.
I have an excellent of a Rok painted by the Wizard that I will post later.
