My uncle had a cylindrical sliderule. 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.
