Any idea?
Please give me time till monday. I am on tour, new source is waiting at home.
OK, no problem. All the best to you
The new source has disappointed me a little, still no reference to the drawing. With some searching i came across the type WD 600. In 1957/58 Wolfgang Denzel started its development of a BMW 600 successor with a design on the 600 chassis. Body design from Italy, I think Michelotti. I think that it is a drawing of this model. Afterwards it becomes the BMW 700 with self-supporting body.
Sorry, no connection with Wolfgang Denzel and Michelotti
has E. Palm designed a new version for his 600?
Not Palm
Graf Goertz?
I knew, you will solve that puzzle! Correct! One more point for you!
Thanks very much for the point and the highly interesting puzzle. The point was a surprise, I simply launched a trial balloon. The leap from the 507 to the "Big Isetta" is quite big. But my ambition was aroused because my parents had an Isetta and then two 700s. I had my first, semi-legal road trials with this fleet. I add one more drawing.
Is that the name "Zetta" written beneath the BMW roundel on the front?
It looks like that too, but I don't have a detailed information.
No, it says Isetta like on the production car. This last drawing was made by Goertz for an Isetta redesign.
Description at BMW Classic: "Designzeichnung BMW 600 (Vorstudie) Exterieur, Albrecht Graf von Goertz", 1956 (design drawing, preliminary study)
Back then they probably thought of naming the enlarged car still an Isetta.
