Long before the war there were engines that were equipped to run on kerosine with a bit of water after being warmed up on gasoline. In the late '50s I worked in a small lumber mill. On days when there was no work, the Owners son and I (Owner too, sometimes) used to fool around with an old steel wheeled Massey/Harris that was built this way, but since the manifold heat system was rusted solid, all we ever ran it on was gasoline, IIRC it had two small tanks for gas and water, and a much larger one for kerosene.
