Surrounded by his hot air engines, Dale is a great builder/collector. What you see at GEARS is about 1 % of the old engines and models he owns! One of the 4 new models since last year is the Heinrici Hot Air engine, with the red flywheels seen to the right in this photo.
I'm not sure where "model" ends and "full size" begins, but Dale has every size Rider/Ericsson Hot Air Pumping Engine that has ever been made, whether it be model OR a "real" engine!!
