Ernest H Buehl’s OX5 ID Number was 17.
The Quiet Birdmen is an invitation-only club.
Ancient and Sacred Order of Quiet Birdmen was a source of information about this organization but the webpage seems to have disappeared. The English Wikipedia has a very nice article.
Buehl also belonged to the OX5 Club. Although Buehl came to the United States as a leading expert on the BMW IIIa engine, he later became known for his association with the OX5. Undoubtedly, this came about because the first plane Ernie ever personally owned was powered by an OX5.
Buehl was present at the first general meeting of the OX-5 Club, held at Latrobe Airport on August 27, 1955, and he was among the first to apply for membership. His membership number was 17.
