Well, another inquiry.  Can anyone who has read the April 83 issue of 
CRYPTOLOGIA and who has some side information on TYPEX tell the world whether
the article by Deavours&Kruh is definitive?  I know it is an unreferenced 
first-shot study based on inference from photographs, but how much did they get
right and wrong?  

One thing's for sure: the system is A LOT like ENIGMA.  So, we know that it 
WAS NOT the German ciphers that were to blame for the Allied cryptanalytic
victory but rather (as we suspected) abysmal key management and the fragmented
organization of the NAZI intelligence systems.  ENIGMA actually seems to have 
been potentially the stronger crypt...    It would be interesting to learn 
what SIGABA was all about - besides "stepping switches".
