Build by Paul Munig or Manch from Berlin.
It has 1 water cooled (by a radiator) engine in the front driving the front wheels and
1 engine the back for the propeller that was cooled with fresh water.
In the photo is the early version.
That version with very narrow wheels was clocked with a water speed of 70 km/h (?)
The later version has a wider body and a more boot shaped bow.
The top land speed was 130 km/h
There ware plans for a trip around the world, but it stayed at plans.
This vehicle is lost in time.
