The Espacenet search results page inclusive of this patent gives the priority date 1910-06-17. This date, and only this date, is also found on the original. It makes no reference to any predecessor, though it neatly fits within the Société Antoinette wing warping family of patents dated at around this time. The original Swiss document here is an "Exposé d’invention", incidentally. The date is being treated as the date filed. Though Patent FR-1909-421500 deals with an apparatus of wing incidence variation and control, which may pertain to wing warping per se, the diagrams differ significantly from those found within this Swiss patent's original document. We are weighing these factors. This Swiss patent is another offspring relative to the elusive Patent FR-1909-07-01 Société Antoinette.
