The Stearman 4 is an American commercial biplane that was manufactured in the 1920s by Stearman Aircraft. They were marketed at the time as fast and luxurious executive transports and mail planes for about US$16,000.
Stearman Aircraft developed the Model 4 from the C3, adding a deeper fuselage and offering a range of more powerful engines. These features enabled the Model 4 to carry heavier cargo loads. Being larger than the C3, but smaller than the M-2 and LT-1 models, it filled a gap in the Stearman product line. Designer Lloyd Stearman said that it was the best airplane he ever designed. Heaters were provided for both cockpits.
In Canada, Trans-Canada Air Lines (later Air Canada) bought one Stearman HEM - CF-ASM and two L10a Cf-AZY, CF-BAF from Canadian Airways for pilot training and surveying new routes and were used from 1937 to 1939. One of them was sold in March 1939. Wikipedia
