I seem to recall 1950s publications talking of a large percentage of wood being used in the fuselage construction but don't remember seeing too much wood lying around at Toussus. Anyone like to comment?
There's a good article on the Breguet in Aeroplane Monthly (July 1992) by John Stroud and he describes it as an all-metal aircraft.
"The unpressurised fuselage, of duralumin with stressed metal skin..."
