Antique farm tractor utility/work light old red paint

Old, Great Depression vintage, 6 volt tractor work light with the mounting bracket and old red paint. We're not sure of the brand or make of tractor that this is for (perhaps an International Harvester or a Ford because of the red paint).

This light measures about 5 1/4" across the light body and has a sealed beam lamp marked "GE" and "Utility".  This seems in good structural condition with wear to the old paint, some rust and pitting from age.
