This specific German Naval Enigma machine was in active use from 1934 to 1945 on the German battlecruiser Lützow. A surviving maintenance book shows that this machine was on board while the Lützow fought against Allied convoys in the Arctic, including the Battle of the Barents Sea in December 1942. | Bletchley Park | Facebook
