Northrop Alpha modified by Stearman
The Stearman-Northrop Alpha 4-A was a single seat low wing all metal monoplane specifically modified (from the Alpha 4) as an air-express mail plane. TWA had eight of them. Except for the prototype (NC127W) all the rest were modified by Stearman in Wichita, Kansas. They were used by TWA for the shipment of perishables (such as flowers and medical equipment) on coast to coast schedules, and served the airline well until 1935 when their duties were taken over by DC-2s.
