From the NYC Organ page: This one-manual positief organ was built for a lecture-demonstration given by Dirk A. Flentrop in a meeting room of the Waldorf-Astoria Hotel. Mr. Flentrop spoke on "Trends in European Organ-Building" and the organ was demonstrated by Mr. Donald Willing. The organ had six manual stops and pull-down pedals. Kurt E. Röderer, then an employee of Flentrop Orgelbouw, installed the positief organ. Following the convention, the organ was sold to Fenner Douglas for his Oberlin, Ohio residence. Mr. Röderer moved the organ to Oberlin, and then decided to stay in the U.S. The Flentrop organ was later acquired by the Oberlin Conservatory of Music and is extant (with two added pedal stops) in Fairchild Chapel, as shown in the photo.
