Weserflug We 271
An almost forgotten equivalent to Grumman's Widgeon and Goose family.
In 1934 Rohrbach Metall-Flugzeugbou was taken over by Weserflug (the fourth largest aircraft manufacturer in Germany even though you probably have never heard of it), and Dr.Rohrbach became technical director. The only in-house Weserflug design to be built, the single We 271 was produced immediately before WWII. After initial testing and minor modifications it was eventually shot down in 1942.
