Four spar fittings from the 1905 Wright flyer, used to maintain structural support or to offer attachment points for wire reinforcement or for strut supports and wing ribs. The long flat piece measures 5.25 x .5, and was designed to hold the wing ribs to the spar; they were bent, formed, and attached at the leading edge of wing ribs to provide curvature. The smaller pieces had various attachment points. Also includes a drive chain link produced by the Diamond Chain Co., Indianapolis, marked “155,” representing the type of block chain used in the Wright Flyer’s engine. Various scattered rust to parts, otherwise overall fine condition. These originate from the family of Louis P. Christman (1893–1972), chief production engineer of the Wright Aeroplane Co., who was given the parts for his work in restoring the 1905 Wright Flyer. RR Auction COA.
