I think this might be Engelbert Zaschka's collapsible (Faltauto) car from 1929.

Strike that.  Zaschka's collapsible car was a three wheeler.  I still think it is a collapsible car, but perhaps one by Hans Seehase from 1921.

[Wendax]

As you found out yourself, your Zaschka guess is wrong.

Hans Seehase is one of the names I was looking for. You certainly found the right car and the same source I have. But I think there is an error in that article. At first, the car doesn't look very collapsible to me, especially if you compare it with Zaschka's and Onnasch's cars. Furthermore, there is a strong connection between Seehase and another man, of whom it is known that he built a car of similar technical data in 1921.

Locked for you to tell me the missing name.

[4popoid]

I'm not sure what name you are looking for.  That the name Paul Baer relates to the puzzle car engine has already been established, so I can only assume it is not Paul Baer who produced some cars in the period 1921-1924.  A Baer engine was also used by Hans Keitel in his designs, but that name has also been mentioned and ruled out.

In 1921 Hans Seehase worked for Joseph Sablatnig, whose factory produced aircraft.  I believe that Sablatig was later involved  in producing some cars, but I don't know if they had Baer engines, and, in any case, this was after 1921.

Also, some cars (Pawi) were produced in 1921 by Paul Victor Wilkem, but I don't know if he had any relationship to Hans Seehase, nor if his cars utilized Baer engines.     

[Wendax]

As usual with multiple choice, the correct answer is the one that is strictly ruled out. Joseph Sablatnig is the name I was looking for. Hans Seehase was employed by Sablatnig, and Sablatnig did build one single 11 PS Baer-engined prototype car in 1921. It would be too much of a coincidence that Sablatnig and Seehase each built a car of their own, especially of similar layout. And as there is no mention of a Seehase car in literature I think the puzzle car is the Sablatnig prototype of 1921.

After more than one year, I call this puzzle solved and award one more point to you.
