Solved: Wendax 528 - Neumann-VW convertible

[Wendax]

Looks nice.

For one point, please respond and identify this car by naming its base and its builder.

[RayTheRat]

If I read the German text correctly, it's an early version of Wilhelm Neumann's Kubelwagen-based custom, built in the DDR before unification.  The site I found it on is REALLY hard to navigate.

[Wendax]

Yes, it is. Built in the early 1950s.

One point for you.
