The photo is of a Couzinet 70. The Couzinet 10 is an earlier twin-engine airplane. The Couzinet 70 Arc-en-Ciel ('Rainbow') was built as a first example of the three-engined, aerodynamically refined, cantilever low wing monoplane designer René Couzinet thought offered the safest long range passenger transport, for example on the South Atlantic route. Only one was completed, though other, similar aircraft of different sizes and powers followed.
