Ed Bertschy’s Paper Steam Engine

This free card model is offered by Bertschy's Paper Models, USA. It is based on a CAD drawing of a Riches and Watts nominal 2˝ horsepower vertical A-frame double acting simple slide-valve steam engine circa 1870-75. The CAD drawing was by Richard Adamek; the drawing is available as part of Richard's Old Engine House website. The model is fully working, and can be run on a puff of air.

It used to be available on Ed's website at:


With the disappearance of his website from the Internet, I.S.S.E.S. is offering it as a free service to the steam engine and modeling community. (Ed had placed it in the public domain and encouraged others to use, distribute, modify, add to and otherwise share it.)
