The Potez IX was an early airliner produced in France in the 1920s a further development of the SEA IV that Henry Potez had co-designed during the First World War. The design mated an entirely new fuselage to the wing and tail structures of the earlier military aircraft. This fuselage was very deep nearly filling the interplane gap and carried within it a fully enclosed cabin with seating for four passengers.
Made by Potez.
It is the successor of the SEA IV .
