Wright Brothers - Original Wright Flyer Component Drawing by LP Christman, w/assistance from Orville Wright.

You are bidding on an original component drawing of Wright Flyer components drawn by Louis P. Christman, with assistance by Orville Wright.

The mathematical data and other notes shown were done when Christman returned to Dayton and conferred with Colonel Edward Deeds and Orville Wright.

The original owner (Cowan Auctions) where I bought this from relates that these working drawings and notes/calculations were done before the final drawings of the reconstruction were produced.

Biographical and Historical Background

As an employee of National Cash Register, with his experience in aircraft and machine design, Louis P. Christman was called upon by prominent engineer and inventor, Colonel Edward Deeds, to undertake the restoration of the 1905 Wright Flyer, which resides at Carillon Park, Dayton, Ohio. Christman was given the opportunity to work closely with Orville Wright in order to produce an accurate set of drawings for the 1903, 1904, and 1905 Wright Flyers. Since no complete drawings were ever produced by Orville and Wilbur Wright during the building and flying of the planes, it was required that Christman travel to Washington, D.C. to the Smithsonian Institution to take measurements and make drawings from the original 1903 Flyer that is displayed there and to discuss these drawings with Orville Wright.

Christman worked closely with Orville Wright to produce an accurate set of drawings.

Good Luck and Happy Bidding!
