Fairbanks-Morse, Throttle Governed, Open Crankcase

One of the engines shown at Boonville in July. This Fairbanks is a forerunner of the later engines used in oilfields all over the U. S. The oilfield engines had a closed crankcase, and tapered roller bearings for the mains, plus a condensing radiator on top. This one sounds about the same as the oilfield engines due to the throttle governing.
