The Bernard 120 seaplane (French) : a 1400 hp single-seat monoplane racer
This is a 1931 NACA aircraft circular, issued by the National Advisory Committee for Aeronautics as a technical report on the Bernard 120 French single-seat monoplane racer. The pages are photographic plates with numbered figures and captions for a technical audience of engineers. The photographs show the seaplane's floats, wing structure, and engine mounts, giving a designer clear views of riveted metal construction and aircraft framing.
