This is a complete and original museum-quality WWII German Enigma machine in excellent working condition.

The serial number A7424 indicates that it was made by Heimsoeth and Rinke in Berlin in 1937.  This Enigma includes five rotors (I, II, III, IV, and V). All five rotors carry the serial number A7424 and match the serial number of the machine. This Enigma machine was used by the Germans before the outbreak of WWII when the German military was expanding in violation of the Treaty of Versailles. This machine would also have been used by Germany after the outbreak of WWII in 1939 through the end of the war in 1945.

Although it is more than 75 years old, this Enigma machine is an excellent, museum-quality example of a 3-rotor Army Enigma (a.k.a. Heeres Enigma or Enigma I). To allow the buyer to use the Enigma, a battery holder that accepts standard flashlight batteries is included as are copies of the original Enigma operating manuals, Dr. Thomas Perera’s book Inside Enigma, and a CD-ROM titled The Story of the Enigma: History, Technology, and Deciphering.

This machine was used by the German military during WWII, but it escaped any major damage and appears to have been stored in a dry environment since the end of the war. All of the rotors have refurbished to original specifications using as many original parts as possible with serial numbers reset to match that of the machine and reflector. All of the internal wiring of the Enigma as well as the wiring of the rotors and reflector have been checked and verified to work just as the machine would have upon issue to the German military in 1937. The finish on the oak box has been lightly restored to stabilize the wood. The machine and the oak case are in excellent condition and show wear characteristic of machines that were in use during the war (see the photographs below).

Successful Allied code breaking efforts against the Enigma cipher machine by the Poles, British, and Americans is attributed with shortening the war by as much as two years, saving thousands of lives, and denying Hitler the time needed to perfect an atomic bomb.

This Enigma machine includes a replica spare rotor box that is shown in the pictures below.

This Enigma has been in our collection for more than 10 years and was purchased from a collector in Germany. It is located in the United States.

This is a very fine working example of one of the most important pieces of history from WWII.

Original German Enigmas like this one are extremely rare and hard to find because most of the Enigmas were destroyed during or at the end of the war. Since they are so rare and historic, the prices paid in several recent sales of Enigmas have been widely publicized and consequently, the values of Enigmas have increased dramatically. In 2015, a 3-rotor German Army WWII Enigma sold at open auction by Bonhams for $ 269,000 US Dollars with the buyer’s premium factored in.  Many of these Enigmas were sold in as-is condition with obvious parts missing. All of the Enigmas sold on this website are complete and in working condition although, since the Germans used brass electrical contacts instead of gold, silver, or platinum, perfect operation on every keypress can not be guaranteed.
