Meanwhile some more facts have come to light. The car was built in 1934 for race driver Eugen Stösser. It is not a modified 303, but the chassis #46534 was a one-off, the engine was reduced to 1098 cc and placed further back, so that a Zoller supercharger could be placed in front of it (see the first four pictures below). In 1936 it was sold to Stiller, who changed the engine and added cycle wings as well as an aerodynamic front axle cover (see last picture below). Stiller sold the car in the early 1940s. After the war a two-litre engine was fitted, a windscreen and a roadster top added, and the rear was modified featuring 190 SL rear lights. The car has been carefully restored now.
