            Airplane & Motor Corp. was founded in 1919 by W.B. Kinner to
            produce radial engines.  The company also produced light
            general and sport aircraft. Kinner went bankrupt in 1937 selling his aircraft
            rights to Timm Aircraft and engine rights to a new Kinner Motors. 
            The new Kinner produced thousands of engines for trainers during World
            War II. The second Kinner Motors was sold to a scooter
            manufacturer in 1946. |
