As always, with Spanish patent on Espacenet, we a have an extreme lack of data, and, as always, we have reason to believe that the priority date data showing up with this patent in the inventor's name-based search results is actually the filing date of this patent, in Spain, rather than the actual priority date.
This likely descends ultimately from designee Patent DE-1911-11-16 Otto Albin Budig, or possibly from Patent DE-1912-05-04 Otto Albin Budig. The former is somewhat more likely, based on phraseology specifically around "airplane", rather than "aircraft" or "flying machine".
