Dornier Do L Delphin

The Dornier Delphin (Dolphin) was a centre-hulled, single-engine, high-wing monoplane seaplane produced in the 1920s. The pilot had an open cockpit on the upper part of the hull behind the engine, which gave him limited visibility. Produced in three versions: Cs II Delphin I; Do L Delphin II; Do L Delphin III. source wikipedia
