This all Paper Steam Engine model was designed by Ed Bertschy using cad drawings of a completely restored Riches & Watts Nominal 2 1/2 hp A-Frame double acting simple slide-valve steam engine, circa 1870-75. The engine it was based upon was salvaged and restored by a Mr Richard Adamek. The models scale is roughly 1:19. There are 13 pages of assembly Instructions with a further 29 pages of assembly Illustrations. I want to thank Mr. John Wagenseil for this nice find!
