Found this engine here in Sweden. REOs are extremely rare here, maybe we have a handful. The story about the engine is that a farmer bought it during WW2, only for using the axels in order to build a trailer (cars where rather worthless here during WW2, since gasoline was on ration and the army had seized the most commonly sized car tires). The farmer kept booth the engine and body in his barn. Someone bought the body in 1959, but the engine remained. My question: What year is the engine, and what model was it mounted in? It is a straight eight, flathead. I can read REO and CLOUD on the side (maybe there are more letters behind an oil filter container (I believe it is). Plate reads R800-977.
