For many years, the identity of the builder of the Harding was hard to confirm. The Harding was discovered in a storage shed in Pamperin Park, west of Green Bay during the 1950s. It had arrived there when one Samuel B Harding was hired by the Works Progress Association to build a shelter on land donated by the Pamperin family. The Pamperins lent Harding some money, and Harding provided the car as collateral, later abandoning it. The Harding has a long wheelbase of 335cm (132 inches), and was powered by a 6-cylinder Wisconsin engine developing 60bhp. Samuel B Harding owned a foundry producing boilers and steam engine equipment. It is believed that approximately half a dozen Hardings were built. The lone survivor was on display for many years at the Reynold's Museum in Alberta Canada. In 2007 Mike West purchased the car and was restoring it to a roadworthy condition.
