Very interesting materials! I've come here from Wikipedia. I've always wondered how simple yet powerful these cipher machines were... The messages are still hard to attack despite the machines were invented about 100 years ago... Not even in 1940's

Please correct my previous entry - SK (End Of Transmission) is "dit dit dit dash dit dash". Sorry for the typo, Morse code is an audio language, not a written language.

Please correct this small error: In Morse Code, end of contact is SK (sent as "dit dit dit dash dit") sent as one letter, NOT VA "dit dit dit dash dit dash). In Morse code, there's a difference between SK and V A, as SK implies End Of Contact, and "V A" has no implicit meaning.

Dear Michael.

Just stumbled across your great site. Many thanks for such an informative site. I look forward to seeing more.

I am seeking a digital or photo copy of 2 particular code books with the tables in them. One is the Kenngruppen Buch and the other is the Kurzsignalnuch. Do you know of a source?

Take care and keep well.
