Preserved at the Militaire Luchtvaart Museum-MLM, Kamp Zeist from 1976. Moved to the Nationaal Militair Museum-NMM in 2014.

Delivered to the US Army as 56-4021. Supplied to Spain under MDAP as Z.6-2. Returned to the USA as 56-4021. First noted at the Museum in 1986 and last noted in 1999.

Hiller introduced a three person cabin with the round bubble canopy in the UH-12C Raven model. Re-designated OH-23C in 1962. Kentucky National Guard Raven 56-2340 is pictured on a short stop at Bowman Field.

This type one of the relatively few exhibits at this super museum that was not operated by the German armed forces.

On display at the airshow. Looks like the crowd forgot to clean up after themselves.

Preserved OH-23C of the California National Guard, U.S. Army.

The first helicopters flown on behalf of the Dutch army by the air force were 35 OH-23B Ravens. A single 'fishbowl' OH-23C, 57-6521, arrived in May 1959 and here it seems to hover through the Museum of Military Aviation. Unfortunately the MLM was replaced by a National Military Museum where army vehicles occupy most of the floor space.
