In 1929 a two-place cabin biplane was the concept of Capt Charles R Bowers. Design work was done by Harold L Scholl, formerly of McCook Field, and J W Van Cleve. Money was put up by insurance broker Stedman plus Howard and Hugh Woolverton. They bought out (Clyde W) Shockley Flying Service and incorporated as Rainbow Flying Service and Rainbow Aircraft Corp.
Built at South Bend IN., USA, the biplane was registered NX294V c/n 1 and powered by a 75hp Rover engine.
