No one knows with certainty how manufacturing mogul John Gladden, founder of the Mustang Motorcycle Corporation (1946-1965), selected the name. Some say he thought of wild horses. Others say it stems from the P-51 Mustang fighter plane. Both stories make sense, but we like the one about the P-51. Gladden Products made parts for World War II combat aircraft, so it seems logical that the P-51 Mustang could have been part of the calculus that created the Mustang moniker. The museum has a full line of vintage motorcycles to include Pony, Bronco, Stallion, Thoroughbred and Trail Machine models.
