Right, Smudge - its the Couzinet Arc-en-Ciel.
The model no. is more of a challenge since the model 70 got changed several times and rebuilt radically at least once. The picture of the model shows it with the Hispano engines, so my guess is that the pic shows the model 71 or 72 flying banana (same plane as the model 70, but they changed the fuselage, wings and tail)
I see we're in ground effect at the present - how about this?
