There are many versions and variatons of the Enigma,
e.g.
Crypto-variations:
- three or four wheels
- number of wheels coming with the enigma
(wheels could be changed, normally they
came in an external box with up to 8 wheels.
selection of wheels was part of the key)
- connections within the wheels
- construction of the wheel (1 or 3 "carry hooks")
- with or without plugboard
- 26 or 28 characters
Technical variations:
- with or without external display
- kind of power supply
Equipment variations:
- kind of wooden box
- kind of manual/instructions
- does it come with a codebook?
- kind and color of painting
Historical differences:
- commercial or military version
- how is it/the box labeled
- whom did it belong to
- what was it used for
- date of manufactoring
- for which encryption/key changing protocols
was it used for
