Going by fromwien's post the Helicamper may have been a one-off, as the two other Fendt-Kleinwagen prototypes were different cars looking more like a Goggomobil.
Based on the accounts of a former Fendt employee and Karl Ummenhofer's daughter, Herrmann Fendt purchased three of these incomplete vehicles and had them completed as Helicampers, so this was not exactly a one-off.
But I doubt Fendt ever intended to produce what were essentially Libelle continuations. Considering how the timing of this little project coincided with the Goggomobil-style prototypes, it was more likely seen as a convenient opportunity for some quick and inexpensive preliminary research into the possibility of microcar production.
I agree totally with "Wendax", but don't have any picture of a white and blue Fendt Kleinwagen, only of a dark red one (picture attached)
You should've saved that one for a future puzzle!
