National Security Agency: German Cipher Machines of WW2

German Cipher Machines of World War II. By: David P. Mowry 

Along with breaking the Japanese diplomatic cryptosystem, usually referred to as "PURPLE," probably the greatest example of Allied cryptanalytic success in WorId War II was the breaking of the German Enigma machine. This cryptodevice was used by all of the German armed forces as the primary cryptosystem for all units below Army level or the equivalent. As D-Day approached, other German cryptodevices, the SZ-42 and the various T -52 machines, assumed great importance since they were used by the higher commands of the German armed forces. Many references to these German machines in the histories fail to provide information on what they looked like or how they worked.  Another group of cryptodevices, those invented by Fritz Menzer for the Abwehr (Counterintelligence), have received little or no notice in the literature and are unknown to the public. This brochure is an attempt to remedy both lacks.  This is an excellent 31 page non-fiction publication with an amazing amount of fascinating facts and photographs. This is truly a must have for those collecting NSA memorabilia. There is No Reserve on this item.  Please email me with any questions.
