Built in 1931 for the Champion Spark Plug Company. Flown by Captain Lewis Yancey 1931-32 in demonstration flights, one of them being a flight over the Gulf of Mexico from Havana, Cuba to the Yucatan Peninsula of Mexico. It was then on display at the Chicago Museum of Science & Industry until it was sold off after WW2. It was eventually discovered in a barn and was acquired by Steve Pitcairn, who restored it to flying condition. Steve is seen in the slide taxiing out for takeoff at the 1986 EAA Convention, which was one of the first public flying displays of it after restoration.
