It was a pleasure meeting you in Madison, Robert. The hat on top of your feather vane is a nice touch. 🙂

Ralph Thompson and Harve Stuart are 2 of the primary early 20th century fan motor patent contributors to Robbins & Myers. So far there is no specific patent for your fan, but if you notice the timeline on Thompsons patent filing and issue dates, it will make one give strong consideration if he was the designer. R&M's use of patent pending, and actual patent issue dates on their tags was strange to say the least.
