Typical of airliners of its time, it seated five passengers within its fuselage, whilst the pilots sat in an open cockpit above. Of conventional configuration, it was a single-bay bi-plane of equal span and unstaggered wings, with fixed tailskid landing gear. Originally designed for a Lorraine-Dietrich engine, this was changed to a Bristol Jupiter in service. After their withdrawal from airline use in 1936, some were used by the military for a while before finally becoming training targets.
