It had about a dozen "rules" that rotated around the central cylinder, with different gratings on the opposite side of each rule. And the central cylinder had at least a dozen, probably 20 or more, gratings. That yielded hundreds of combinations. I wish he had bequeathed it to me. I have no idea what became of it.
