A very rare and unusual set of Enigma rotors (serial number K590D, rotors II, IV and VI). Discovered among communications equipment disposed of in Germany at the end of the War, it has a complex history. According to production records it was issued to the German Condor Legion during the Spanish Civil War. Afterwards, the machine were returned to Germany and rewired on 7 March 1944 for use by the Axis-aligned Croatian Home Guard (Kroatischen Landwehr — Hrvatsko Domobranstvo). Two of the rotors (V and VI) were produced separately to rotor II as extra rotors. Whilst records make no mention of the existence of rotor VI, these extra rotors were supposed to have been destroyed in 1944, but for unknown reasons were not. These are the only known surviving Enigma rotors issued to the Croatian Home Guard. The existence of spaces for nine turnover notches and the existence of rotor VI suggest that the rotors may have never reached Croatia, and may have been rewired yet again as Enigma KD rotors. However, this theory has not been confirmed.
