From approximately six sets of castings made by Ken Brennerman in Oakland in the mid 30s, this is the only known surviving engine. A set of partially machined castings were found at a garage sale in California in 2002 and eventually ended up with Dick Pretel. Aware of Ken Brennerman and the history of his engine, Dick decided to complete the castings to represent the original, but incorporated more modern engineering and machining techniques, too. This single-cylinder overhead valve engine burns gasoline on spark ignition and was completed in 2003.
