Far left is Randy Rockwell and the engine far left is a Frisco Standard model built by Rocky from castings by the Banke's. Randy "proved" the drawings for the Frisco when he built this model and noted his findings for drawing corrections. The red engine is a 5/16 scale of a Root and Vandervoort horizontal "screen cooled" engine. The first green engine is a 1/2 scale model of a 1 hp hopper cooled R&V engine. The final engine to the right is a 5/16 scale model of a 4 hp R&V Vertical "screen cooled" engine. Castings for all of the R&V engines are available from Randy.
