Three Horten Ho 9s were constructed prior to wars end: the V1 sailplane, the twin 004B powered prototype V2, and the serial production prototype V3 by Gotha-Friedrichsroda. Myhra has taken 150 photos of these Ho 9 versions from his collection, along with several dozen digital images, and has put together a unique Ho 9 photo collection.
