An archival engineering flightline photograph providing a detailed study of the forward nose assembly of the Ryan NYP Spirit of St. Louis at Dutch Flats, San Diego. The image details the hand-turned damascened aluminum nose cowl with dark script "Spirit of St. Louis" lettering, the Wright J-5C Whirlwind 9-cylinder radial engine with exposed rocker arms and pushrods, and the aerodynamic fairings on the forward landing gear struts. The damascened spinner and duralumin propeller blade are captured against the San Diego horizon, documenting the handcrafted metal finishing executed by the Ryan factory crew under Donald A. Hall's supervision.
