The Bernard 20 C.1 (French) : a single-seat pursuit monoplane
This 1929 NASA technical report on the Bernard 20 C.1, a French single-seat pursuit monoplane, is a set of engineering drawings and data issued for aeronautical researchers and engineers. The pictures are plain line drawings: three-view orthographic plans of the fuselage, wing and tail, and numbered cross-section diagrams with hatched areas and lettered callouts. A designer could borrow their clean, measured linework, the labelled-callout layout, and the sleek profile of a 1920s monoplane.
