On the far left is Richard Williams TWO cylinder Fairbanks. It is the same engine as the 3 cylinder, but with one less cylinder. Many parts are interchangeable. The second engine we think is owned by Jim Kittelson and is a horizontal R&V, castings sold by Rocky Rockwell http://www.home.earthlink.net/~randyarockwell/ >
The engine on the right is a (I think) Red Devil owned by Larry Derry. Castings for this engine are available from Shelf Pet Models http://www.shelfpetmodels.com/ >
