ENIGMA M4 A fully operational four-rotor ("M4") Kriegsmarine Enigma Cipher Machine. Berlin-Wilmersdorf, Germany, Heimsoeth und Rinke, 1942, seized from the Bauaufsicht der Kriegsmarine in Trondheim, Norway, after the capitulation of Nazi forces there in 1945 Four-rotor ("M4") Kriegsmarine Enigma cipher machine, serial number 5124/JLA/42, complete with Beta rotor (M3174), 3 aluminum rotors (IV, VI, & VII) with serial numbers (VI: M8423, IV, VIII: M10138), and C reflector (M3174), each rotor with 26 positions labeled with letters. Housed in the original oak case (13¾ x 11¼ x 6¼ in.), with leather handle, case with hinged front panel stamped "Klappe Schleissen" opening to reveal ebonite Steckerbrett [plug-board], outside of case and inside of lid with matching metal plates reading "M 5124." Control panel with standard raised "QWERTZ" keyboard of 26 Bakelite keys in white on black backgrounds, lockable rotor cover, battery compartment and 4V power socket and key, removable light panel with letters A-Z lifting to reveal 26 light bulbs, Steckerbrett with 12 original patch cables (10 plugged into the Steckerbrett and 2 spares stored in lid of case), lid with 10 spare bulbs, green contrast filter, spare patch cables, original paper instruction label, (stamped serial 5124), and stamped "Admiral Norwegen | Kommando der Marine Station Ostsee" above the instruction label. [WITH]: additional aluminum rotor (II: M5569) in secondary oak storage case (5¼ x 10¼ x 5 in.), outside of case and edge with matching metal plates reading "M8423," inside of lid with the effaced stamp of "Kommando de Marine Station Ostee," and the additional stamp: "Marineoberkommando | In Norwegen | Druckschriftenverwaltung," [AND] Original German telegraph key (D.R.P Junker), and five facsimile user manuals. A VERY FINE AND FULLY OPERATIONAL EXAMPLE OF THE FAMOUS GERMAN FOUR-ROTOR ("M4") KRIEGSMARINE ENIGMA CIPHER MACHINE, WITH PROVENANCE TRACING BACK TO OCCUPIED NORWAY. THE RAREST AND MOST DESIRABLE OF ALL ENIGMAS, THE M4 WAS ONE OF THE HARDEST TO DECRYPT. VERY FEW M4 MACHINES SURVIVED THE WAR, AND TO FIND ONE THAT IS COMPLETE, WITH TRACEABLE PROVENANCE, STILL IN SUCH PRISTINE CONDITION, AND FULLY OPERATIONAL IS RARE INDEED. The M4 Enigma machine was an electromechanical cipher machine specifically developed for use by the U-boat division of the German Navy (Kriegsmarine) for communication with the naval bases, where it played a pivotal role in the Battle of the Atlantic. Admiral Karl Dönitz, the commander of the U-boat fleet seriously doubted the security of the Enigma after several unexplained losses, and had the secret M4 model developed specifically for his fleet. The M4 was ready around May of 1941, and by February of 1942 all M4 machines had been distributed with the new operating procedures placed into effect. The present example was one of 15 Enigma machines in daily use at a communications bunker and headquarters for the Admiral North Kuste at the Kriegsmarine base in Trondheim, Norway. Following the occupation in 1940, this became the largest German naval base in northern Europe, and the base housed the 13th U-Boat Flotilla, and some 55 U-boats. Norway was an important strategic asset for Germany, as it facilitated access to iron ore from Sweden, and to the North Atlantic and Arctic Oceans. Critical information passed through the Trondheim communications bunker, such as weather observations sent from U-boats in the north Atlantic, among other things. The assorted serial numbers found on the aluminum rotors in the present machine are a good indication of consistent wartime usage, as German operators frequently swapped out rotors from other machines. While the codebreakers at Bletchley had been reading messages encrypted by the 3-Rotor machines for some time, the introduction of the M4 caught them completely off-guard, shutting them completely out, and it took them a full 9 months to catch up and solve the new code. Few Enigma machines survived the War intact: the Germans destroyed them as they retreated, and for decades after the war governments around the world kept close control over Enigma technology (indeed two of Turing's wartime papers on cryptography remained classified until 2012). So secure was the system believed to be that some governments, unaware of the work of Bletchley Park, continued to use Enigmas after 1945. The M4 was a variation of the 3-rotor Enigma I machine used by the Wehrmacht (German Army & Airforce). It accepted 3 standard rotors and a narrow fourth rotor in combination with a narrow reflector. The two narrow components allowed all four rotors to fit into a modified three-rotor Enigma chassis. It was issued with eight standard rotors, the first five having wiring identical to the rotors issued with the three-rotor Enigma-I. Two narrow fourth rotors, Beta and Gamma, were also issued with each machine. With the fourth narrow rotor in the "A" position, the M4 became functionally identical to and could communicate with the three-rotor Enigmas used by other branches of the military. With its stricter operating procedures and the ability to select from among 8 standard rotors and two thin fourth rotors gave the M4 a much higher level of security, foiling the Allies' previously successful decryption of the U-boat signals. Compared with the more common 3-rotor Enigma, the M4 had many significant differences beyond the added rotors. It had a different ring-setting mechanism on the rotors, a lockable rotor cover to keep the wheel settings secret, a removable lamp panel which allowed for the inclusion of a printer (Schreibmax), and a power socket for an external power source. The M4 also had a removable top, and two metal brackets that allowed the machines to be lifted out of the compartments in the U-boat radio rooms. M4 Enigma machines were produced in much smaller quantities than the three-rotor Enigma I machines. In addition, multiple M4 Enigmas were deployed with each U-boat and support ship, and the majority of these were lost when their boats were sunk in combat or scuttled by their crew at the end of the war. Furthermore, German Enigma operators were under strict orders not to allow the enemy to capture any Enigmas; this meant that many Enigmas were stripped of their rotors and destroyed, with many thrown into lakes or oceans to hide any remaining parts. THIS PRESENT MACHINE SURVIVED FOLLOWING THE SURRENDER TO ALLIED FORCES BECAUSE GERMAN OPERATORS WERE KEPT AS PRISONERS OF WAR IN A BARRACKS NEAR THE TRONDHEIM BUNKER THROUGH 1947, WITH THE AIM OF TRAINING THE ALLIES TO OPERATE GERMAN TECHNOLOGY, INCLUDING THE ENIGMA M4.

Enigma I A fully operational three-rotor Enigma I cipher machine, in rare Panzerholz case. Manufactured in München by Ertel-Werk für Feinmechanik in February 1941. 3-rotor Enigma I cipher machine, serial number A00789/bac/43E, complete with reflector and 3 bakelite rotors (I, II, and IV) all with matching serial numbers (A00789), each rotor with 26 positions labeled with numbers, housed in the original black metal Panzerholz case (10 1/2 x 13 1/4 x 6 inches). Case with removable metal lid, revealing control panel with standard raised "QWERTZ" keyboard of 26 glass and metal keys with white on black backgrounds, light panel with letters A-Z and hinged rotor cover lifting to reveal 26 light bulbs, reflector & rotor compartment, and battery compartment, bake-lite Steckerbrett (plug-board) and 12 patch-cables, inside of lid with original printed instructions ("Zur Beachtung!"), and original wooden extra bulb holder. Some wear to components consistent with, and indicative of field use including: lettering on ring above power switch worn off, rotor cover no longer present, green contrast screen no longer present (not uncommon; the original screens are made of a material that off-gases and is highly corrosive to the machines), removable metal plate in front of plugboard no longer present, lettering outside of case which would have read "Chiffriermaschinen" worn away, Despite this, this machine is in exceptional working condition, with all original parts and fully operational. A FULLY OPERATIONAL ENIGMA I, IN ORIGINAL CONDITION, IN A RARE PANZERHOLZ CASE. The Enigma I, often called the "Heeres" Enigma, was used by the German Heer (Army), the Luftwaffe (Air Force), and later, by the Kriegsmarine (Navy) before the introduction of the "M4" 4-rotor machine. The serial number A00789/bac/43E of the present machine indicates that it was manufactured in 1941 by Ertel Werke, a German company manufacturer of scientific and mechanical instruments founded in 1802. Ertel-Werke was located in Munich’s Westend from 1911 on, until it was burned down completely in a bomb attack in April of 1944. It was the exclusive manufacturer of the Enigmas in the rare metal Panzerholz cases. Patented in 1918 by Arthur Scherbius, the Enigma machine uses three electromechanical cipher wheels, each with 26 contacts at either side. The three rotors would be placed in pre-arranged positions, and the user would then type in a plain text message using the keyboard. The machine would encipher the message, and each corresponding encoded letter would light up on the light panel. The enciphered message would then be sent to the receiving party, usually via Morse code. The receiving party would then decipher the message, using another Enigma machine with the rotors set to the same position as the first. The rotors of all Enigmas were interchangeable, and indeed, rotors were swapped out very frequently. The fact that all three rotors on this machine match each other, and match the machine’s chassis indicate that this machine was used in isolation from any others. The Enigma machine set a challenge that was answered by the remarkable team at Bletchley Park, whose achievements provide one of the most compelling stories of World War II. Breaking Enigma was the work of many, including Polish cryptographers who had already begun to decipher Enigma traffic before the war; naval forces who risked their lives capturing Enigma machines and code books; Alan Turing and other mathematicians with their revolutionary models for deciphering; Tommy Flowers and other mechanical geniuses who designed 'Colossus', the world's first programmable digital computer, at the GPO Research Centre at Dollis Hill in north west London; the hundreds of Wrens who operated the Bombes and, later, Colossus machines that made possible the daily decrypts. Their work saved countless lives and had an enormous impact on the submarine war in the Atlantic, the North African campaign, and the Normandy invasion; the work of Bletchley Park is often said to have shortened the war by two years. Furthermore, by coming to the understanding that to defeat Enigma it was necessary to mechanize much of the work of decryption, they helped to inaugurate the computer age.

The Enigma I, also called the "Heeres" Enigma, was used by the German Heer (Army), and the Luftwaffe (Air Force). Patented in 1918 by Arthur Scherbius, the Enigma machine uses three electromechanical cipher wheels, each with 26 contacts at either side. The three rotors would be placed in pre-arranged positions, and the user would then type in a plain text message using the keyboard. The machine would encipher the message by passing current through each rotor (twice) and the plugboard, and each corresponding encoded letter would light up on the light panel. The enciphered message would then be sent to the receiving party, usually via Morse code. The receiving party would then decipher the message, using another Enigma machine with the rotors and plugs set to the same position as the first. Keying the machine would alter the setting of the rotors, the rotors were interchangeable, and the plugboard added further permutations, so whilst the machine would always perform the same conversion with the same setting, overall there were a total number of 159 million million million possible daily keys. The Enigma machine set a challenge that was answered by the remarkable team at Bletchley Park, whose achievements provide one of the most compelling stories of World War II.
