This 5-cylinder radial model aircraft engine was designed and built by Henry Parohl, of New York, circa 1960. The engine is 11”-long, 10”-wide, and 9”-high. Most of Mr. Parohl’s engines incorporated gravity fed lubrication systems. Prior to running the engine, the operator would fill the small, transparent reservoir ahead of the number one (top) cylinder with motor oil. Then, with its spark ignition turned on, the engine would run on regular gasoline. The oil would slowly feed from the reservoir into the engine for lubrication.

This model is believed to be the only 5-cylinder radial engine that Parohl designed and built. It is not known if Parohl worked from drawings or sketches, but none have been located.
