Wow, that *is* hardware crypto!
Those devices were practical right up until people started using automatic
devices to crack codes (i.e. WW II).
Terrific pictures. First item is a 'code wheel,' though I'd only seen them
with 2 or 3 alphabets before that one. The second item looks like a strip
cipher. The third looks like some complicated variant of a Jefferson Wheel
(pardon my USA & U.Va. bred prejudices).
