im not to sure on how valuble/ invaluble it is

Given its an original 1909 aircraft engine, (despite its lack of successful flight) it would seem to be very important and of great significance, perhaps not equal to AV Roes original triplane, but certainly one of the few original survivors from those early pioneers?

I am becoming convinced the engine is a normal combustion engine, given its original intended use in a car, and no apparant details of a steam boiler in the drawings or design discussion in the research material sent to me.
