Abstract

This paper concerns the very first “classical” Enigma from 1924, with rotors, reflector and lamp display. A description is given of the Enigma machines bought by the Swedish General Staff in early 1925, of the competition regarding the first standard crypto machine for the Swedish armed forces, and of some later developments.
