The Francois Villiers marine pursuit airplane
This is a 1927 NACA Aircraft Circular, a technical government report by the National Advisory Committee for Aeronautics, documenting the Francois Villiers marine pursuit airplane through photographs of its engine bed, fuselage, and float-equipped flights. The page of six numbered photographs shows structural framing, a close view of a wing, and two seaplanes at rest and on water, useful to designers for vintage aviation layouts, technical plate arrangements, and monochrome engineering documentation.
