Who knows this car?
Experts?
Too hard for the experts...
German?
Yes.
BIG HINT:
It´s been named after its constructor and was built in some numbers by a differently named company...
Benz Parsifal?
Much more obscure...
Any connection to Willy Seck and Scheibler?
Not Liliput, not Scheibler.
The car model is named after its constructor, but the main brand was the name of the company that has built it finally.
Although the pictures I know show a different car, I'll give it a try. Is it the Klingenbergwagen, built by AAG (later NAG)?
No, but it´s the right attempt to find it out.
BTW: Wikipedia is listing this vehicle, too...
Is it a Wenkelmobil, built by Automobilwerke Schneider & Co, Berlin?
It was built in different layouts, even with rear engine. The only pictures I know show the version I posted as a puzzle before:

Yes!
It´s a Wenkelmobil 9/10PS 4-seater, model 1906-07.
