Bill Stout was a developer of all metal airplanes and when Henry noticed that endeavor he employed Stout and the Tri-Motor came about as a result. In later years Stout, on his own, but with Ford Motor connections for mechanical components built his Scarab. The Scarab was powered by a flathead V8 that was rear mounted and in appearance seems to predate what is commonly known as a mini-van.
A scarab is a dung beetle, but I've never run across the name used by Ford, only Stout. What time frame would this have been?
