It is possible the name of this engine was acquired from drawings or a construction article from an early publication named Model Craftsman, and castings may have been available as well. This engine has a cast aluminum crankcase and cam box with a machined cast iron cylinder and head. It has spark ignition with an adjustable timer in the front and an unusual rocker arm assembly. Oil mixed in with the fuel lubricated the internal parts, but the rocker arm assembly must be manually lubricated before operation. Built in 1938, the designer and builder care unknown. The engine is 4”-long, 3”-wide, and 5”-high.
