[DR HOUSE]

Hi Bob,

Five letter code groups were used by just about everyone.  One reason  
was they got the maximum amount of information across public telegraph  
networks at the lowest possible cost.  The second reason was that the  
code groups were meaningless unless you had a current decode table.
Industry used this as well as the military.  One of the most  
successful espionage efforts in history was the long standing VENONA  
operation the Soviet Union used from the 30s to the 70s for their  
spies to send secret messages to Moscow.  A British intelligence  
officer and an American mathematician who could think in Russian  
figured it out or they might still be using it today.  If you get a  
chance to see SECRETS, LIES, AND ATOMIC SPIES on PBS NOVA watch it.   
Our museum helped produce the segment.  If you watch closely you can  
see my fingers on a M14 strip printer and our executive director's  
stomach next to an IBM card sorter.  I have a first generation VHS  
tape sent to me by the director that I need to convert to DVD before  
the tape turns to noise.  There is also a good book The VENONA PAPERS  
published by REGNERY

Best,
Don

Jerry Proc's site is quite the interesting read, I've browsed it many
a time. It's a great reference for various crypto systems. If any one
else is interested, John Savard has a good set of pages in his
cryptographic compendium on telecipher machines:
