Enigma message sheets
Before and during WWII, many different types of message sheets or forms
were used for writing down plaintext, encrypted and decrypted messages
as they were sent by means of the Enigma cipher machine. Below is a
non-exhaustive overview of the messages that were in use at the time.
Most of the forms can be downloaded as a PDF file by clicking
the image.

This form was issued in October 1939, just after the outbreak of WWII,
and is nearly identical to the one above, except that a slightly different
Fraktur typeface was used. This probably caused by the fact that every
printer at the time had its own Fraktur typface.
