There’s a wonderful low-rent documentary, “Rockafire Explosion!” about the creation, salad days, and strange afterlife of the robot bands.
In the course of the documentary, a die-hard fan is seen buying one of the two remaining units direct from the factory, which was* a creepy frozen-in-time picture of the firm in its heyday, featuring tools left of worktables when word of the layoffs came through, and pools of toxic sludge.
The Visalia unit looks like a re-dressed band.
*The remaining employee, the owner, blew the place up while working on a synthetic fuel.
