In February 2022, European Airlines Rob Mulder celebrates its 15th anniversary. At our 5th anniversary in 2012, we published “Flying with my photos”, that turned out to be very popular. We have decided to present a guide of civil seaplanes and flying-boats in Norway between 1919 and 1940. For this publication,The author has teamed up with Kay Hagby, Norwegian aviation historian and expert on the civil air register in Norway, and we publish a high-quality softback publication with photographs. We hope this publication will fill a gap for the scale model builders and those interested in civil aircraft in Norway.
