Does anyone else have one of these? Does anyone know who
manufactured this? Does anyone know what it is called?

I purchased one of these back in 1992 at a toystore in a
Florida mall. I paid $4.99 for mine. The tags says:

WrisTwist (tm)

The puzzle is still in its pristine state and the color progression is:

Red-Blue-Green-Yellow-OrangeRed-Violet-Orange-LightGreen
