A flown grease cup used on the Curtiss JN-4 'Jenny' and the DeHaviland DH-4 during World War I, and later used for the restoration of the Wright Brothers' iconic 1905 Wright Flyer III. The cup and hinged lid measures 1.5″ long and has a threaded bottom. In fine condition. This was one of several parts originally obtained by Louis P. Christman for his work in restoring the 1905 Wright Flyer. Christman worked closely with Orville Wright to produce an accurate set of blueprints for several Wright gliders and flyers.
