After reading the August/September 2018 issue, I have to comment about the "Patent Page" section. Aermotor did in fact produce an engine with the wooden base as in the patent that you highlighted. I've attached a picture from a 1911 ad. I don't think they built that engine for very long, maybe only a year or two.
