Welch OW-1

The Welch OW-1 and the similar OW-2 were American three-seat open biplanes designed by Orin Welch in the late 1920s.^[1] The OW-1 was powered with a 90 hp (67 kW) Curtiss OX-5 and the OW-2 was powered by a 150 hp (110 kW) Hispano-Suiza 8A, both of which were water-cooled V-8 aero engines.^[1] Four OW-1s were built (NC817, NC4205, NC5105, NC6838), one of which was converted into the first of two OW-2s.^[1] The first OW-2 was later modified into a 5 seater, before being destroyed in a hangar fire in November 1929. The second OW-2 was given the civil registration NC11142.^[2][3][1]
