Bletchley Park 18-7-25 137 Abwehr Enigma G - serial no. G312
Abwehr Enigma G - serial no. G312
This model G is smaller than most German military Enigma machine. Like the early commercial models of Enigma, this machine does not had a plugboard on the front. Unusually, the Enigma G’s small rotors are controlled by gears, which move them in an irregular pattern.
This type of machine was used by the German Military Intelligence (Abwehr). Due to the lack of plugboard, the ciphers created by these machines were less complex than those produced by later models. They were therefore more vulnerable to the analogue decryption methods developed by GC&CS during the 1930s
