Galion Iron Works Company was founded in 1907 by four brothers in Galion Ohio. Galion produced road building and construction equipment of many types and designs including some experimental machines one of which this may be. I did some research not finding any old photos or even a reference to this particular design piece of equipment but I do calculate from a reorganization timeline that this item was manufactured between 1923 and 1945 when they discontinued pull behinds. Enjoy this “older than most of us” piece of early history and your search.
