Please excuse my poor translation from Dutch.
The GMG II was built by brothers Jakob and Phillip Muller from Griesheim. The firsts example D-1420 was built between 1935 and 1938. It is powered by an Anzani engine producing 35 horsepower.
The photo at left was taken in 1933. It was built by Engineer School (university) Weimar. ... von Loessel and Hermann Kohl.
The driveshaft connects to a Hirth HM60R-1 engine.

I wonder if they did any work with the Horten brothers.
