This highly important three-rotor Enigma deciphering machine was used by the Nazis during World War II. It is believed that acquisition of an Enigma, and the subsequent deciphering of the German codes by the Allies, shortened the war in Europe by at least two years. Examples of Enigma machines are exceptionally rare and almost all known models are in museums.
Built and designed by the Germans, the Enigma Machine came in a few varieties and where code creating and deciphering machines. Originally commercial units since 1926, they are quite possibly the most complex non-computerized code machines ever made (though they are a mixture of mechanical and electronic parts). The Germans used them to send coded messages during the war, relying on the machine’s ability to have over a billion combinations.
Probably the only Enigma machine available for sale in the world right now is available by Rau Antiques who recently acquired one. In very good cosmetic condition, and in working order, this three rotor style Enigma Machine was made around 1937. Price asked for it by Rau is $112,500.
