I got this double sided painted sign off a friend of mine at Iowa Gas. Heavy metal, never saw one like it before. I think it may be a sign that was used on an Alamite grease gun rack similar to the one pictured. The shape is about the same but the mount holes are different. Did anyone else ever see one in use or hav any more info on it? I was told at the show a company made grease gun racks that could be branded to a specific company.
