Seen One Of These?

This beauty was at Midwest Old Settlers and Threshers last year. A close look revealed that I had never seen an engine like this one before. Instead of a reciprocating steam engine, this machine has a rotary steam engine. Luckily for the visitors to Old Threshers, it was fired up and operated. If you are wondering what kind of sound a rotary steam engine makes, just press your lips together and blow. Maybe the sound is the reason these did not catch on.
