This KZ IV was built in 1944 (the only other example of the type was OY-DZU, built in 1949) and used as a flying ambulance for Zone-Redningskorpset. In March 1948 this aircraft took off with the Swedish Count Folke Bernadotte in order to negotiate with the Nazis for the release of some 30,000 internees of the Theresienstadt Ghetto.

The aircraft was used by the Zonen organization, (Zone-Redningskorpset air ambulance service), and is named Folke Bernadotte after the Swedish Count who negotiated the release of Nordic citizens from Nazi concentration camps in the Spring of 1945.

No date of this picture is known. By 1976 it had received a small Lufthansa logo underneath the cockpit. The aircraft was severely damaged in May 1979, but repaired in the nineties.

Outstanding among the delightful collection of KZ types kept at the Danmarks Flymuseum is the KZ IV twin-engined ambulance aeroplane from 1944, one of only two built. Considered by the museum as one of their most prized exhibits, KZ IV OY-DIZ was designed and built for the Danish flying ambulance service known as 'Zonen' and benefitted from the concession allowed by the wartime occupying German forces for medical flights. Powered by two Gipsy Major X 130hp engines, it possessed excellent short-field performance. It crashed in 1979 but after an extensive rebuild, remains in flying condition.
