The Portland show provided the first opportunity for Keith Kinney, Evansville, Ind., to put his hands on this new addition to his engine collection. The 7 hp Thermoil Model U was built by Hercules and sold by Sears. The Cummins diesel (with Cummins injector) engine was built in about 1922. The engine is complete, including the factory original cart and clutch pulley. Of several thousand built, perhaps 200 survive.
