content: Unlike most of its rivals, this engine was equipped with L-head rather than overhead valves. It powered Burgess, Curtiss, Wright, and Sturtevant seaplanes, many of which were purchased by the U.S. government. It was also used in several privately-owned land planes. The artifact was removed from the Herring-Burgess aircraft that is in the museum’s collection.
