"More than 10,000 of these V-8 engines were manufactured, most of them for use in Curtiss JN-4 Jenny trainers. After World War I, thousands of OX-5s and Jennies were sold to the public at a fraction of their original cost to the government. In addition, during the 1920s, the OX-5 engine powered airplanes developed for civil aircraft by Waco, Laird, Curtiss, Fairchild, Alexander, Travel Air, and many other firms."
Doesn't look like a Jenny so we'll just have to slog through every other US aircraft of the 1920's I guess
