The Westland "Widgeon III" "Cirrus II: or "Genet II" engine
A 1927 NACA Aircraft Circular from the NASA Technical Reports Server, issued as a technical report for aeronautical engineers and aircraft designers, giving the general arrangement of the Westland Widgeon III monoplane. The page is a set of engineering drawings with three orthographic views, dimensions in feet and inches, a table of wing, stabiliser, elevator, fin and rudder areas, and a caption noting the Cirrus II or Genet engine options. A designer might take from it the clean, labelled line-drawing convention of technical plans, with dimension lines and tabulated specifications.
