* ENIGMAS & other Cipher Machines FOR SALE:
As cipher machines have taken on increasingly important roles in world history, considerable interest has developed in collecting and studying these early technological innovations.
For over 20 years we have been actively searching for examples of the Enigma cipher machines that the Germans relied on to keep their military communications secret during WW-2. Very few Enigmas survived the war and since the Allies were commanded to destroy every one that they found, it is a real challenge to find them. Each Enigma has a story to tell and careful research and disassembly can provide clues to its hisory.
We work with a group of dedicated historians, collectors and technicians to uncover Enigma history and we make it available through EnigmaMuseum.com. A Virtual Museum like this is the ideal format for making these rare and interesting historic instruments available to view and study.
We have put the information in our book and CD-ROM Enigma Library. We give lectures and demonstrations and provide Enigmas as displays for museums and props for media and occasionally sell an Enigma to help defray our expenses. More recently, we have found other historic cipher machines including a fascinating Russian Cold War era Fialka cipher machine.
We attempt to display as much of this information as possible in our frequently-updated museum pages and we welcome comments and questions.
The German Enigma Cipher Machine played a critical role in the history of WW-2. We have documented every aspect of the Enigma in our CD entitled The Story of the ENIGMA: History, Technology, and Decoding
and in our new book: Inside ENIGMA and other Historic Cipher Machines. Ordering information is presented at the bottom of these linked summary and introduction pages.

ENIGMA AND OTHER CIPHER MACHINES FOR SALE
Please visit our "For Sale" page for a look at the Enigma and other Cipher Machines that ew are currently offering.
Poland was aware that Germany would probably invade them first and built a cipher bureau to try to read enciphered German messages. The Poles were the first to determine how the Enigma machine worked and how to go about decoding its messages. When Poland was invaded, the Polish mathematicians were already
helping the Allied forces develop strategies and machines which allowed them to read many important German messages during the war.
A team of codebreakers working at Bletchley Park in England and initially using the wiring data and a replica Enigma machine supplied by the Poles was able to decode most of the enigma-coded messages used by the German military even though the Germans changed the settings of the machine. The code name for the deciphering operation and the intelligence derived from it was "Ultra".
Every year the surviving veterans of the operations at Bletchley Park meet at Bletchley Park for a reunion.
Here are some pictures of the 2009 Bletchley Park Reunion.
Each letter typed into the enigma machine's keyboard was converted to some other letter of the alphabet and displayed in a lighted window. Since the entire mechanism rotated each time a letter was entered, pressing the same letter three times could produce three different encodings. The encodings were produced by hard-wired code wheels and patch panels. The three code wheels could be mounted in a variety of positions and each one could be set to any letter of the alphabet. In addition, a patch panel on the front of the machine could be set up in many ways, making a vast number of combinations of cipher keys possible.
The Enigma cipher machine consists of a battery and a series of keys and
switches which determine which of the 26 light bulbs will illuminate one of
the 26 letters of the alphabet.
If you type the word ''HELLO'' on the keyboard (the plaintext message),
letters ''AZRWK'' (the ciphertext message) may be illuminated by the
light bulbs. The ciphertext message ''AZRWK'' is then sent by telephone or
radio to a receiving station and there an operator types ''AZRWK'' into
another Enigma machine which illuminates light bulbs ''HELLO'' (The original
plaintext message).
In order for this to work, the Receiving Enigma machine must be set to the
same STARTING POSITION as the Sending Enigma Machine was set to. Since there
are heptillions of possible starting positions, even if an enemy has an Enigma
machine, it is virtually impossible for them to decode the ciphertext since
they would not know the proper STARTING POSITION.
Here is how the initial starting position is set before sending the first
message of the day:
SETTING UP THE DAY'S STARTING POSITION:
1. Set the Sequence of Rotors ( Code Wheels ) on the rotor shaft.
(Set the Position of the 3 Numbered Rotors or Code Wheels from left to right
on the rotor shaft.)
(Any three of the 5 numbered rotors can be placed in any of the three
positions on the shaft.)
There are therefore 60 possible sequences of three rotors.
2. Set the Number or Letter Rings on each of the 3 Rotors (Code Wheels).
(Set the 'Ring Setting' of each Rotor or 'Code Wheel'.)
There are 26 possible settings on each of the three rotors.
This gives 26 to the third power = (17,576) possible settings.
3. Set the Number or Letter to be visible through the 3 windows at the
start of coding.
(Set the 'Starting Positions' or 'Ground Setting' of the three Rotors.)
There are 26 possible settings in each of the three windows.
This gives 26 to the third power = (17,576) possible settings.
4. Insert Double-Plug Cables into the Plugboard (Patch Panel).
(Set the Plug-in wire Connections on Plugboard.)
There are anywhere from 0 to 13 plug wires which can be inserted into any of
the 26 sockets.
This gives: Sum from p=0 to 13 of 26!/(26-2p)! x p! x 2 to the p power
= (532,985,208,200,576) possible settings.
Combining these possibilities give us a total of
26,672,901,348,424,004,787,290,112 or about 10 to the 26 power possibile
starting settings. (Other ways of calculating this figure produce different
totals.)

A short list of Internet Web Resources, Films, and Books devoted to the Enigma.
This video is also included in:
"THE STORY OF THE ENIGMA CD-ROM REFERENCE LIBRARY CD-ROM".
`
These exceptional films are among the most important discoveries of my career:
The two original German movie film clips show the Enigma actually
being used by German Soldiers.
Obviously the Germans did not want people to know that they were using
Enigmas for most of their secret communications so very few still
photographs of Enigmas in action have been found. Finding one is a
remarkable event. The discovery of these two original films is an even more
remarkable and important event.
I first saw tiny pieces of these movie clips in 2011 in the wonderful DVD:
"The Spies Who Lost the Battle of Britain: The Story of British Radar
and how the Germans Nearly Discovered it".
It is a very well researched and produced documentary of the
development and deployment of Radar in the early days of WW-2.
The DVD was filmed and published by Brian Marshall of boffinstv.co.uk and it is
sold by the Radio Society of Great Britain (RSGB) www.rsgb.org.
Brian was kind enough to track down the brief clips from NARA in his DVD
and he sent me more complete film segments. They are truly remarkable...
Thanks, Brian !

Here is an example of:
another marine Enigma that
was recovered from a submarine off the East coast of the United States in
2002.
After careful cleaning and expert restoration much of
the dirt and corrosion has been removed and the machine begins to appear as it
once looked.
The internal mechanism and rotors, however, are still not
in very good condition.

80 PRE-WW-2 * GERMAN ENIGMA CIPHER MACHINE:(25KB) This
three code wheel cipher machine called the "Enigma" was manufactured from the
early 1930's throughout World War II. The code was broken by the Poles whose
work helped the Allied forces develop strategies and machines which allowed
them to read many important German messages during the war. Note: the word
cipher is also spelled cypher which is a primarily British variant.
A team of codebreakers working at Bletchley Park in England was able to decode
most of the enigma-coded messages used by the German army even though the
Germans changed the settings of the machine. The code name for the
deciphering operation was "Ultra".
Each letter typed into the enigma machine's keyboard was converted to some

This rare model of the enigma cipher machine has four adjustable wheels. The
right three code wheels (German 'walze') are similar to the standard enigma
machine wheels and the left wheel is actually a completely adjustable
reflector (German 'umkehrwalze') which can be set to any one of the 26
possible letters. The machine was also supplied with an external and internal
display as well as a multiple-voltage power converter transformer in a
separate box which converted voltages ranging from 110 - 250 Volts, AC to the
required 3.5-volts to operate the lamps. The remote display made it possible
for the officer-in-charge to read the decoded text without the cipher machine
operator being able to see it. This was useful for top-secret messages.

119 ABSOLUTELY INCREDIBLE ENHANCED ENIGMA-INSPIRED CIPHER
MACHINE MADE BY TATJA VAN VARK, EDE, THE NETHERLANDS:(35KB)Tatja has
always been interested in all kinds of mechanical and electronic devices. She
was particularly fascinated by the Enigma machine and wanted to own one but an
original was out of reach and she decided to build her own. After studying
a short description of the principles of the Enigma,
she decided to design and build an improved cipher machine and a printer
similar to the German Schreibmax printer which worked with the Enigma.
Tatja has no formal education in electronics or mechanics. As she puts it: "I
wanted to own a coding machine and now I do." Building it took about 8
months. No wonder when you see how many parts are inside, and everything had
to be home made. For example, each of the rotors has 509 individual parts.
She is particularly proud of the helical gearing in both the cipher machine
and the printer. Tatja makes everything herself including the varnish which
is made from all natural ingredients.
A nearby museum has asked her to restore their Enigma machine and to
give a lecture and demonstration of both machines. She is now working to
restore the museum's automatic telephone exchanges and carrier wave
equipment.
The machine now has the looks and uses many of the priciples of the original
Enigma but it has much stronger coding capabilities. She says:
"I will bet that nobody in the next hundred years will be able to decipher
the short message I created with my machine:
GUK59 XBOFJ
-AFF1 SGU65 0-KME YKCL7 76PRO LIKNY /WVSZ X-JYI OS6GN 9GLYL
CTOSE -UBO6 OFD7P I+M3J
Here is a collection of photographs of Tatja's fascinating cipher
machine and of some of the other amazing instruments that she has built
as well as a photograph of this extraordinary woman. Please visit

Here are some very interesting and informative INTERNET SITES AND REFERENCES DEVOTED TO THE ENIGMA:
120 SWISS 'NEMA' VERSION OF THE GERMAN ENIGMA
MACHINE:(15KB)
The NEMA worked on the same principles as the Enigma. The 4 active rotors
each had an easily adjustable ring-setting wheel that could be changed as
though it was one of the rotor thumbwheels. All these thumbwheels gave the
erroneous impression that the NEMA had 10 rotors. The military or war version
was supplied with two additional rotors, 'E' and 'F' that were stored inside
the top cover. The NEMA was made by Zellweger A. G. in Uster.
An interesting feature of this machine is a remote light panel which
can be positioned in such a way that the person typing in the
coded letters can't see the message as it is decoded. This machine
is apparently also capable of feeding its output into a printer.

RUSSIAN COLD WAR ERA M-125 FIALKA CIPHER MACHINES:
170 RUSSIAN COLD WAR ERA M-125 FIALKA CIPHER
MACHINE:
Very little information has previously been available about this interesting
machine. I have produced a set of hundreds of detailed photographs and descriptions of
my Fialkas and their disassembly as well as rotor wiring and rotation advance
data for the two different Fialka rotor sets. They may all be viewed in the
THE STORY OF THE ENIGMA CD.
If you have a fast internet connection, you can see much of this information
by selecting the LARGE scrollable picture-filled pages from the following
Fialkia Menu. The size of each page is given for each selection. If you have
a slow internet connection, you can read the following introduction and click
on the pictures and read the descriptions that follow the introduction.
INTRODUCTION TO THE RUSSIAN FIALKA:
GENERAL DESCRIPTION:
The Fialka is generally similar in design to the German Enigma cipher machine
but it has 10 rotors with 30 Russian characters/contacts instead of the 3 or 4
rotors with 26 letters/numbers/contacts in the German WW-2 Enigmas. The first
version of the Fialka, the M-100 was produced in the 1930s and it was followed
by the M-105 and then the M-125 models described here. The M-125 models
include the M-125-MN and the much more complicated M-125-3MN. (M-125-3MP3 and
M-125-3MP2 models have also been reported. They appear nearly identical
with the M-125-3MN but may have different keyboards.) The codename "FIALKA"
is the Russian word for "VIOLET".
INPUT AND OUTPUT:
Instead of illuminating light bulbs to display the output characters resulting
from inputting characters into the keyboard, the Fialka prints the output
characters on paper tape and simultaneously punches holes in the tape in 5
level characters resembling those of a Baudot teletype machine tape. The
Fialka also includes a paper tape reader for use in rapidly inputting
characters that have been punched into a paper tape.
CARD READER:
The Fialka incorporates a card reader which allows punched paper cards to be
used to set internal coding parameters. These cards replaced the clumsy,
difficult-to-set, and therefore error-prone plugboards of the German
Enigmas.
DIRECTION OF ROTOR ROTATION:
The Fialka rotates each of its 10 rotors in a direction that is opposite to
that of each neighboring rotor. Most other cipher machines have rotors that
all turn in the same direction. The pins that control the
rotation of individual rotors are described and the locations of all pins for
all rotors are given in tables in this rotor description link:
UNIQUE REFLECTORS:
The reflector at the left of the rotor stack is different from the reflector
in an Enigma and different in each Fialka model. Unlike an Enigma which has a
completely self-contained reflector, the reflector in the M-125-MN Fialka has
one bundle of wires extending down from it. The reflector in the M-125-3MN /
-3MP3 has three bundles of wires coming out of it.
MULTI-LINGUAL OPERATION:
The M-125-3MN and M-125-3MP3 models differ from the M-125-MN models in that
they incorporate multi-lingual keyboards and some unique and complex switches
that allow the machine to function with several languages.
ROTORS:
There are two different sets of 10 rotors that can be inserted into either
machine. If present, the second set of rotors may be carried in a cylinder
inside the cover of the machines. One set is non-adjustable with fixed ring
settings and a fixed wiring maze. The other set is exceptionally cleverly
designed in that it allows for both the normal Enigma-like changes in ring
settings (the outer lettered ring may be rotated) coupled with the ability to
actually remove the internal wiring maze module from each rotor. Once the
wiring maze is removed, it may be reinserted into the rotor in any of the 30
possible positions and/or flipped upside down and inserted in any of the 30
positions to give a total of 60 unique wiring circuits. In addition, the
wiring maze module itself may be removed from the rotor and inserted into a
different rotor.
There are at least two series of rotors. Each series has unique wiring and
rotation blocking pin locations. Each series is documented in the links that
accompany this publication. One wiring and rotation option is found in the
series of rotors with the numerical prefix '3K'. At lease some of these
rotors are known to have come from Poland. A second wiring and rotation
option is found in the series of rotors with the numerical prefix '6K'. At
least some of these rotors are known to have come from the former
Czechoslovakia. It is possible, therefore, that the different series were
used in different countries and/or by different military entities. All rotor photographs and wiring data are given in this rotor
description link:
DESCRIPTIVE PHOTOGRAPHS:
The following photographs should help to clarify the comments and descriptions
above: Hundreds of additional Fialka photographs, descriptions and wiring and
rotation data tables are available in THE STORY OF THE
ENIGMA CD and some may be viewed in the links listed in the Fialka Menu at
the top of this section. Much higher resolution versions of all of these
Fialka photographs are available on a separate Fialka CD.

rotor removal:
170s1u Removing the rotors reveals the
complex drive cog mechanism that causes each rotor to revolve in a different
direction from the adjacent rotor:
The lower horizontal bar activates cogs that pull forward on the bottoms of
rotors 2, 4, 6, 8 and 10 (counting from left to right) and rotate them so that
the tops of the rotors move AWAY from the keyboard.
The upper horizontal bar activates cogs that pull back on the bottoms of
rotors 1, 3, 5, 7 and 9 (counting from left to right) and rotate them so that
the tops of the rotors move TOWARD the keyboard.
A set of 10 spring-loaded arms with rollers holds the 10 rotors in their
detent positions.
170s1v A view of the 10 rotor stack after
removal from the Fialka. The rotors may be removed from their shaft and
moved to different positions as shown in this photograph:
170s6e The 10 rotors have a fixed
internal wiring maze connecting the input contacts to the output contacts.
It may be uncovered as shown, but it is not designed to be modified:

(42 additional photographs and descriptions can be found in this link):
(90 additional photographs of the disassembly of the Model M-125-3MN / -3MP3
Fialka can be found in this link):
This model is MUCH more complex than the M-125-MN model.
it has the following additional features:
1. A multilingual keyboard.
2. A mechanical switch along the right side of the keyboard
that modifies keyboard function.
3. A 3-position lever on the back of the Fialka that modifies paper tape
punch operation.
4. A large matrix switch that alters the wiring of the programming matrix and
therefore the effect of the programming cards.
5. A rotary switch located under the base of the Fialka.
6. A position on the switch located to the right of the input wheel that
stops rotation of the rotors and character counting as characters are typed
into the keyboard.
7. An extended copyholder.

u_171s1m A closer view of the 10 rotors with the index bar raised to permit
removal of the rotor stack.
The two rounded levers that push the reflector on the left and the input wheel
on the right inward have been pulled forward so that the reflector and input
wheel may be pushed outwards to allow the rotor stack to be removed.
These rotors are the Non-Adjustable rotors. The multi-adjustable rotors
are described later under accessories and in the special detailed section on
rotors and rotor movement.
u_171s1y The drive mechanisms that produce the rotation of alternate
rotors.
The lower horizontal bar activates cogs that pull forward on the bottoms of
rotors 2, 4, 6, 8 and 10 (counting from left to right) and rotate them so that
the tops of the rotors move AWAY from the keyboard.
The upper horizontal bar activates cogs that pull back on the bottoms of
rotors 1, 3, 5, 7 and 9 (counting from left to right) and rotate them so that
the tops of the rotors move TOWARD the keyboard.
A set of 10 spring-loaded arms with rollers holds the 10 rotors in their
detent positions.
u_171s1n The 10 rotor stack of Non-adjustable rotors is shown here after
removal from the Fialka. The rotors may be removed from the shaft and
reinserted in any order:
u_171s6e The internal hand-wired set of connections between the input contacts
and output contacts of this Non-Adjustable rotor is called a wiring maze.
It can be inspected or repaired by removing a metal disc as shown here. The
wiring of these non-adjustable rotors is not designed to be changed.
u_170s6p The Multi-Adjustable Rotors can have their modular wiring maze
removed and reinserted in 60 different ways. Their outer ring setting can
also be changed in 30 ways. Details and more pictures are in the links above.

192f RUSSIAN NON-ELECTRONIC SPY POCKET BURST ENCODER:
(25KB)
The coding unit (with the dial) writes the magnetic pulses onto the tape by
direct magnetic induction without the use of any electronic circuitry. Each
dialed-in character rotates a series of permanent magnets past the tape. This
writes the pulses onto the tape and at the end of the dial's rotation, it
advances the tape. This makes the pocket encoder independent of any power
sources and completely portable.

194c RUSSIAN ELECTRONIC BURST ENCODER Model R-014D:
(25KB)
This is a very complex and interesting burst encoder set which operates on
internal batteries and can input, store and send encoded messages at a very
high speed producing a burst of encoded data that keys a radio transmitter and
broadcasts a very short transmission containing the entire coded message.
These extremely short and fast messages are difficult for an enemy to receive
since they are only on the air for a very short time. The short duration of
the message burst also makes it difficult for the enemy to use direction
finding radios to pinpoint the location of the transmitter. The unit was used
with Russian Radio Station R-142. It was part of the "Automatic System for
Field Command" for sending secret information at high speeds with a maximum of
150 Baud. Disassembly of the device reveals a rather unique set of printed
circuit boards that are hinged at the back and open like a book for
servicing.
