EXTREMELY RARE WWII GERMAN NAVAL AIRFORCE SECRET ENIGMA CIPHER MACHINE CODE BOOK COVER.

Revised: 2/18/2013

Please Note: A more detailed and lengthy description of this extremely rare book was not available to us until after the catalog had been printed. Following is that more comprehensive description.

This exceptional code book cover was designed specifically to be used on naval aircraft. It is enclosed in an aluminum outer frame and the inside of each part of the cover contains specific information as well as places to store additional special coding sheets. No other code book cover like this is thought to have survived the war.

The secret code book cover being offered here is a bi-fold container with three sections, each 8-11/16″ high x 6″ wide, made of dark red canvas and leather, bordered in aluminum with original printing on the cover along with the issue number “796”. The outside of the front cover displays a yellow cross that is believed to have been applied to deceive non-German speaking individuals into believing it had something to do with first-aid if the code book was captured. The cover is also marked “Geheim” (Secret) and it is thought that it was to be carried only on designated naval aircraft. The bottom center of the cover is marked with a large spread winged eagle and swastika inside a wreath over “Oberkommando der Kriegsmarine” which indicates that the cover was printed by the naval high command in Berlin in 1939.

The interior pages show black and white printing along with various red ink stamps and red ink writing some of which are updates. Instructions say that it must only be used onboard aircraft of the German Navy. (Like our own navy, the German navy had had its own Aircraft that were separate from the German Air Force “Luftwaffe”.)

Some of the information on the inside of the three parts of the cover is described below:

Left side: (Dates and basic information). The code book cover was originally released in Kiel on June 22, 1939. This code book cover was released by the “Seefliegerhorstcommandantur” in Schleswig on the 4th of July 1940. That means that the command center for aircraft of the German navy in Schleswig, a town in Schleswig Holstein, the northernmost part of Germany released this for use on July 4, 1940. Middle section: (A place to display the Enigma key table) The actual Enigma key table or “Schusseltafel” was to be pushed in under the plastic. Right side: (Specific procedures and codes) This side shows the “F. Au. T.” (The “Funk Aufklärungs Tafel” or Reconnaissance aircraft code table).

The content is broken into sets. In set 1 are: a) Morse code procedures, flag signals and flag tables. b) Aircraft star signal tables. (Star signal probably means broadcast messages to all.) c) Names of the Navy aircraft for radio communication. d) A plastic pocket or bag for storing part B of the key group tables. In set 2 are: a) The actual F. Au. T., Reconnaissance aircraft code table. b) A plastic pocket for storing part of the key group tables.

In the left part of the page is a plastic enclosure for storing the used pages of the memo pad and storing the actual aircraft signal table. In the middle part of the page is the actual daily number table matched to the F. Au. T.- signal tables. In the right part of the page is the removable memo pad. The word Geheim or Secret ! is imprinted to remind the user of the importance of secrecy. There is a correction order dated December. 1941. The last date that can be found in the cover is 2. Feb. 1942.

In addition to the three interior pages, there are four accordion-like ribs with eyelets in the first fold which is reportedly where the pink sheets of code book pages were attached. Much of this information appears to have been used for editing messages before they were enciphered with the Enigma. Flag signals were used ship to ship and aircraft to ship, when they were in visual contact. Careful and detailed translation of all of the pages will certainly reveal new information about how the Enigma was used and adjusted during the war.

CONDITION: This code book cover was almost certainly used onboard aircraft during the war and it shows the scars of heavy use as is appropriate for a well-used military artifact. The 3 parts are sound and intact showing light edge wear and moderate soil. The interior pages are yellowed and slightly brittle but appear to be completely intact. The aluminum binding shows wear and a few small nicks and dings.

Enigma machines themselves are exceptionally rare collector’s items as indicated by the recent sale of a German Army Enigma in incomplete condition for $250,000 (with the buyer’s premium factored in). This code book cover is much rarer than an Enigma. The history of the Enigma is complex. A German engineer developed the first Enigma machines around the end of WW-I, with early use primarily by commercial enterprises. The German Nazi government took over all production and use of the Enigma well before the beginning of WW-II and used it throughout the war. The early Enigma machines used a three rotor system for enciphering messages, then in about 1938 the German Navy improved the security of the Enigma by adding a 4th. rotor.

In about 1932 brilliant Polish mathematicians figured out a way to break into Germany’s military enigma codes and about five weeks before the outbreak of WWII, in 1939, anticipating Germany’s invasion, they presented their enigma decryption techniques and equipment to French and British military intelligence. During WW-II and thanks to the information and machines provided by the Poles, the British were able to keep up with advancements made by the Germans in their encrypting equipment and generally were able to decipher most of the German military messages that they intercepted. The British code breakers at Bletchley Park were the prime movers in this effort, assisted by the capture of German equipment and code books.

This is an extremely rare item that would add great impact to any museum or military collection especially one containing an Enigma and other Enigma-related artifacts.c

EXTREMELY RARE WWII GERMAN NAVAL AIRFORCE SECRET ENIGMA CIPHER MACHINE CODE BOOK COVER. SN 796. This is certainly the most unique and important Enigma-related artifact to have survived WWII. It is the complex and well-used cover of a Naval Airforce Enigma codebook that contained all of the secret settings of the Enigma for each day of the month. These settings were used by every naval vessel, submarine, aircraft and shore station. Each month a new codebook with the Enigma key settings for that month was placed inside this cover. The cover was carried in a German Naval Aircraft where it served the dual purpose of protecting the codebook from damage and providing specific helpful information for the aircraft radio operators who used and programmed the Enigma cipher machine. This exceptional code book cover was designed specifically to be used on naval aircraft. It is enclosed in an aluminum outer frame and the inside of each part of the cover contains specific information as well as places to store additional special coding sheets.

Interior pages show black and white printing along with various red ink stamps and red ink writing that describe various dates of service, instructions, codes and procedures. There are also places to store code book pages and logs. Much of this information appears to have been used for editing messages before they were enciphered with the Enigma and for describing flag signals for ship to ship and aircraft to ship visual communications.
