 This airplane was the prototype for the Fokker F-VIIA-3m and was based at Ford Airfield (now the Ford Test Track in Dearborn, Michigan) and Stout's factory location.Several measurements and photos were taken during its stay.Shortly afterward, partly using the single-engined, all-metal Stout 2-AT Pullman as a starting point, the model 3-AT trimotor was produced using an all-metal construction technique.
