above via: http://www.sportschrono.com/ and some history on it here: http://en.wikipedia.org/wiki/Smith_Flyer is that the Smith Flyer was bought by Briggs and Stratton. The Smith Flyer was an automobile manufactured by the A.O. Smith Company in Milwaukee from 1915 until about 1919 when the manufacturing rights were sold to Briggs & Stratton and it was renamed to Briggs & Stratton Flyer. The Smith Flyer is a small, simple, lightweight, two-seat vehicle with a wooden frame that doubles as the body and as the suspension. A small gasoline engine is mounted on a fifth wheel, or motor wheel, to drive the Flyer.
I didn't know the whole ensemble was called the Briggs and Stratton Flyer buckboard
