Morane-Saulnier WR

 

Apparently, there it seems to have been two (or even three) airplanes which received the WR denomination. The first was a modification of the Type G (though some sources claim it was the Type H) which, was a regular machine fitted with floatplanes. 

It was supposedly designed for the Imperial Russian Navy, but that's not entirely supported as it was most likely a Russian variant with a greenhouse fitted on the sides of the fuselage, ahead of the wing and it wasn't a seaplane. For more information about this one, check our previous post about the Russian Type Gs here. 

Anyway, the type took part in the 1913 Schneider Trophy for seaplane race in Monaco. This WR incorporated wing-warping for lateral control and had balanced all-flying elevators and balanced rudder without the fin. It was powered by an 80 hp Le-Rhône engine. It seems that the Swedish Thulin B also received this modification.

The second Type WR was an armoured airplane designed to meet a 1913 requirement for a two-seat armoured reconnaissance airplane. It was stated that it had to be powered by an 80 hp Gnome engine and the machine should cost at maximum 37.000 French Francs (that's 5,640.00 € - $6414,96). It's not known if any of these machines went beyond the drawing board.
