Munitions Buildings, Washington D.C.
26 Nobember 1936
Dear Mr Rowlett
We intercepted this message intended for the
Japanese Embassy in Washington. Fortunately we
know its beginning:
MESSAGE Z NUMBER
Z FIVE EIGHT Z THREE Z STOP Z
FOR Z INFORMATION Z ONLY Z STOP Z
Unfortunately they no longer use the vowel /
consonant separation.
It is possible to deduce from the indicator (24241)
the following elements
- Direct Mode
- Decipher Mode
- The interrupter wheel position (from 1 to 47) : 38
- The vowel wheel position (from 1 to 6) : 3
- The consonant wheel position (from 1 to 20) : 15
Good luck!
Wiliam F. Friedman
