Nick I took notes from a book about the Enigma machine and it's development back in 1997, of which I have read several. It will take me some while to find the exact book at the library again. The type X machine however was nothing more than an exported three rotor Enigma. The Germans were well aware that the British had it. I am merely citing notes taken verbatum at the library since I had no way at the time of photocopying. I have extensive handwritten notes from numerous sources.

I will answer the question when I have relocated the book.

Three rotor Enigma was also used by German railways, Luftwaffwe base commands, SS Klien Kampfverbande units (mini subs in Adriatic etc) and Heereswaffen (army unit) commands in the field. These codes were frequently read. For example Luftwaffe units reported losses and personnel transfers or received orders by Enigma. The waters are muddied because there was also alternate means of communication not requiring radio transmissions, such as telephonic messages or telegrams.

Having spent much of my spare time for the last 17 years reviewing tens of thousands of ENIGMA decrypts and also Allied Luftwaffe-related SIGINT from the MTO, I've acquired a certain familiarity with the above (except the Reichsbahn stuff)! The "main series" Luftwaffe material also embraces mission intentions and results, periodic strength returns, unit dispositions, movements of aircraft, pilot availability etc. etc. etc. All you need is time and persistence... these messages are an invaluable aid to reconstructing Luftwaffe actvities.

I've also read a lot of books on ENIGMA (finding Hugh Sebag-Montefiore's probably the best overall) but none has said that much about TypeX and they are all hung up on U-boats, I guess because the Luftwaffe traffic once broken into was read fairly promptly and consistently, so the story lacks drama.

Thanks Ed - more expense!

Well Nick, I have a long list of books I want. I try to organize them in order of what I think are the most useful, followed by those that sound less useful. Almost needless to say, that list just keeps getting bigger and bigger

Hello all,

Cryptology has been an interest of mine for many years.
My Computer Science Masters Project in the mid 1970's was based around an Enigma Simulator programmed on a big old ICL System 4 machine (~ 150 sq m of floor space, punch card input, paper tape output, machine code, etc - probably less overall computing power than a PDA of today)
That was my first simulator, many, many more followed.

I can reccomend the following which gives a list of internet available software simulators:

There is info on building your own machine, and a good book reference.

Try a simulator, give you hours of fun, send each other messages !

Regards,

Tony W
