Kinner 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.
