The Weymann-Lepere W.E.L. 10 Observation Airplane (French) : a High-Wing Monoplane
This is a 1930 NASA Technical Reports Server pamphlet, an aircraft report from the aeronautical technical literature of its period, presenting the Weymann-Lepere W.E.L. 10 French observation monoplane. The plates show detailed construction drawings of wing structures, struts, fittings and fuselage joints, plus two photographs of the aircraft in flight and on the ground with a Hispano-Suiza engine. A designer might take the precise line-drawn hardware, crisscrossed bracing and tubular frame geometry as a clean technical vocabulary for mechanical diagrams.
