Used running antique Hercules 4 cylinder flat head gas engine and radiator, model JX4.
Was on a generator, starts easily, sounds good, oil is clean. Tag shows it was rebuilt in 1970
Including trailer axle and springs if you want them, but NOT including iron frame/base.
I believe this model has been used in various Diamond T trucks, forklifts, pumps, welders, tractors and such.
