An archival technical photograph taken beneath the overhang of the Ryan hangar, providing an intimate study of the Spirit of St. Louis nose section without cowl panels. The perspective details the welded chrome-molybdenum steel-tube engine mount truss, the duralumin propeller hub, cylinder valve rocker boxes, and the firewall interface engineered by Donald A. Hall Sr. The photograph documents the accessibility and maintenance configuration of the Wright J-5C radial powerplant during ground checks.
