RE: Spinner question
More specifically, it's a model of the GeeBee R-2 Racer. The R-1 and R-2 were built for the 1932 races. The main difference between the two was the engines. The R-1 had a Pratt and Whitney WASP engine for the Thompson Trophy Race. The R-2 had a Pratt and Whitney WASP Jr. R985. This aircraft was built for the Bendix Trophy Race, which was an endurance race.
On December 23, 1991 Delmar Benjamin test flew his R-2 replica. He essentially pulverized the myth that the GeeBee was a deathtrap.
