The vertical finned cylinder in the rear is an air compressor. All parts have part number cast in with the letter 'C' preceding the number. There is no brass plate and shows no sign of one being attached, but there is a decal. The only identification found are the letters T.S.T. Co. cast in the head, but I think that is the name of the casting company. I hope someone can identify this engine, for it's quite different.
