Lufwaffe Enigma

These days, I've had a love affair with the Enigma machine, reading hundreds of pages about it, watching tens of videos on YouTube. I even watched Das Boot again (wonderful movie!), just because it contains some shots with a 4-rotor type Enigma, although these shots were regarded as a goof, because the 4-rotor type was introduced only after 1 February 1942, after the autumn of 1941, when the film was set.
