T52d, 1st problem

GC&CS - Station X

September 3, 1944

To Deputy Director John Tiltman,

Sir,

I adapted the T52 cipher machine manual to create for the
T52d one.

Thanks to it and thanks to our previous works about this
machine, I managed to encrypt a message by following the
German procedures. This exercise can be used by our teams
trying to decipher encrypted messages with this machine.

Best Regards,

Michael Crum.

=========== Example ==========

I have encrypted the following message with this key:

Inner Key: 4-6, 1-2, IV, II, 5-9, III, 3-7, I, 8-10, V

External Key: 19, 27, 28, 21, 39, 20, 32, 4, 47, 40
(From "K" wheel to "A" wheel)
