Enigma D simulator

Introduction

The Enigma Model D is the most popular commercial version. It was used by many armies during World War II (but also before and after): the Austrian army, the Italian navy, the Spanish army (of Franco). The German Railways, under military control, also used it. In all these variations, the rotors have been rewired.
