**SOLD** This offering is a complete, museum-quality Enigma cipher machine in excellent working condition.

The serial number of this Enigma machine is A01593 / bac / 44 E. This indicates that this machine was made by Ertel-Werk at Westendstrasse 160 in München, Germany, in 1944.  This Enigma includes five rotors (I, II, III, IV, and V). All five rotors carry the serial number A01593, matching the serial number of the machine. This Enigma machine was used by the Germans in the last years of WWII. Enigma machines were manufactured through early 1945 to supply newly formed divisions made up of shattered German forces being pushed back by the Allies.

This machine was used by the German military during the war to send important encrypted messages. It escaped major damage and appears to have been stored in a dry environment since the end of the war. The box is in very good, stable condition and appears to have had some restoration work done to the top. The finish on the oak box has been lightly restored to stabilize the wood.

All five rotors have been rebuilt 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 cleaned of any corrosion, inspected, and verified to work exactly as the machine would have upon issue to the German military in 1944.

A replica ID tag has been placed on the Enigma in front of the keyboard. A fragment of the original tag accompanies this machine.

At the lower left, lower right, and upper right corners of the Steckerboard there are places where fragments of the Steckerboard have broken off. There is also evidence of repairs having been done by a previous owner. (See closeup photographs of the Steckerboard in the pictures below.) We have determined that these missing fragments and the repairs in no way interfere with the operation of this machine and that they do not significantly detract from the appearance of the machine. Many Enigma machines saw service near the front lines of battle and do sometimes show evidence of rough service. Overall, this machine and its oak case are in very good, museum-quality condition and show signs of wear and use characteristic of machines that were in service during the war.

Although it is more than 74 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.

Allied code breakers, including Alan Turing, developed the world’s first computers to break German secret codes. Successful Allied code-breaking efforts against the Enigma cipher machine first by the Poles, and later by the British and Americans, shortened the war by as much as two years, saving thousands of lives and denying Germany the time needed to perfect an atomic bomb.

Enigma machines are extremely rare. German officers had orders to destroy them rather than let them be captured at the end of the war. The Germans had no idea that the Allies had broken the Enigma codes and felt that they had to keep their secret code machines from falling into the hands of the enemy. German soldiers would kick them, hit them with rifle butts, throw them into lakes, and even explode hand grenades inside them when their positions were about to be overrun by Allied forces or in preparation for surrender. 

Relatively few Enigma machines survived the war, and nearly all of these are held by museums and government agencies. Very few of these rare machines are available to private collectors.

This Enigma machine includes a replica spare rotor box, which 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 and available for immediate delivery.

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


This Enigma machines has been SOLD.

Original German Enigma machines 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 buyer’s premium. All of the Enigma machines 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 key-press can not be guaranteed.
