Kinner Airplane & Motor Corp was an airplane and engine manufacturer, founded in Glendale, California by Bert Kinner in the mid-1920s. Kinner's chief engineer was Max B. Harlow who went on to found the Harlow Aircraft Company.[1] It went bankrupt in 1937 and the aircraft rights were sold to Timm Aircraft Co (see Otto Timm). The engine department was rearranged as Kinner Motor Inc in 1938, but folded in 1946. Kinner became the West Coast's largest producer of aircraft engines in 1941.[2]
