Design and development

The
W.F. Stewart Company
was a custom builder of wooden auto bodies. When factory-built steel bodies overtook wood construction, the company broke into the aviation market with the
Stewart M-1
, an all-wood
monoplane
. Sensing wood construction was about to be overtaken by all-metal aircraft, the Stewart M-2 was developed.

The M-2 was an all-metal, twin-engined aircraft with
conventional landing gear
, powered with
Wright J-6
engines. 225 hp
Packard DR-980
engines were later installed and tested.
Townend rings
were used on the re-installed Wright J-6 engines.
