Good morning Mel,
I can see what looks like a pair of lifting eyes ahead of the cockpit, but no sign of struts, so is it a low-wing catapault-launched float equipped mailplane like the Hienkel He.12 or He.58 ??
No sucess in locating any cockpit pictures.
Going to be very busy today, so regret it will have to be Open House in the unlikely event of being correct!
