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.

the wing of OY-NIX (c/n 173004) was used to restore OY-XIE.

The aircraft was built by a farmer Arne Hollænder and Aksel Smidt at Hollænder's farm in Aarre. Therefore, it is known as Hollaender HT-1 for Harald Thyregod but also as Hollsmidt for two builders. The Hollsmidt name is on the nose.

Although looking very original this is the plastic replica, that was at the museum entrance for years. Now it is at the back of the museum, probably to be refurbished.
