The Kinner Airplane & Motor Corp. of California began building 5-cylinder engines in 1919. The company also built light aircraft from 1931 to 1937. In 1939, the company changed its name to Kinner Motors and produced engines for thousands of World War II training aircraft.

At the age of 83, Merritt Zimmerman designed, drafted, fabricated and tested this 1/4 scale model within six weeks in 1994. The engine is 9″-long, 11″-wide, and 12″ high.
