The Welch OW-3 was a 2 to 3 seat, light airplane designed by Orin Welch in the late 1920s.
[1] There were two versions of the OW-3.
The OW-3 Hi-Lift variant (two built) was a two-seat, open cockpit biplane with a modified Standard J-1 fuselage that incorporated a Welch-designed high-lift wing.
[2] The OW-3M (only one built) was an open cockpit parasol monoplane that could seat three people.
