[warren brown]

I'm sticking my neck out here, but I remember reading somewhere there was a commercial version of the enigma machine made in (I think) Czechoslovakia during the 'thirties - even advertised in magazines. It was one of those things that wasn't picked up at the time - but the enigma machine was a derivation of this machine - yet the wartime enigma more spools which increased its 'uncrackability' exponentially... (don't hold this as fact anyone...)
