These Ernst Zündel mislabelings are all false except for the Repulsin depictions. The reasons:   1) Schriever-Habermohl: This is in fact Habermohl's only known submission with a Walterrohr engine and was immediately rejected as impractical. Reconstruction of Schriever's Flugkreisel based on the 1975 Luftfahrt International magazine article 2) The supposed 1941-42 disc fan is not accurately depicted: The true Flugkreisel had 3 kerosene engines around the saucer rim plus two at the SIDES of the craft.   3) The Schriever-Belluzzo disc: Totally false misidentified Henri Coanda Lenticular disc that has NOTHING to do with the Flugkreisel project. This was to be powered by 12 Jumo 004s and was rejected as impractical. A scale model was wind tunnel tested only.   ~Rob Arndt Viktor Schauberger Repulsin A & B
