Stinson Model B

The Stinson Model B was a projected twin-engined executive aircraft that Stinson drew up in the mid 1930s as a development of its Model A trimotor airliner. The American Aviation Historical Society production notes list it with two 245 horsepower Lycoming R680-B6 engines and say that only a mock-up was made. Aerofiles describes it as the twin-engine version of the 1934 Model A airliner with two 245 horsepower Lycoming R-680B engines, built as a mock-up in 1936, and agrees that there was no production. No flying example was ever built.
