I did a search on Fahlin, and found this:
"In 1939 the Nicholas Beasley Aircraft Company sold out to Air Associates of New York, and Ole Fahlin accepted an offer
to move his propeller factory to Columbia, Missouri. The aircraft industry was resurging at the time and the Fahlin
propellers were in demand. This demand increased as World War Two approached and Ole's propeller factory was
producing all types of propellers, especially for the flight training aircraft such as Ryan, Timm, and Stearman, and as the
war progressed the factory also turned out heavy test ’clubs” for the large military engines. The propeller
factory worked full bore throughout the war years, and then suddenly in 1945 the war was over and contracts were
canceled. There was no way to sustain the business with only limited civilian propeller orders (some skis and bows and
arrows were also produced) and the Fahlin Corporation was eventually dissolved."
