Rare surviving Enigma machine expected to fetch £70,000 at auction

A rare early German Enigma machine that WWII codebreaking hero Alan Turing worked hard to decipher is to go under the hammer.

The Enigma 1, which dates from between 1930 and 1938 is also known as the Wehrmacht, or ‘Services’ Enigma, and was used extensively by German military services and other government organisations such as the railways before and during the war.

It is one of the earlier models with just three rotors while later ones had five.
