I’m trying to determine what type of signage may have been originally used on this Gulf rack. I’ve seen examples of the wire rack ones with the handles and top mount signs and the solid shelf battery racks, but I can’t seem to find any examples online of a rack with these type of shelves. They appear to have mounting tracks on the front and back of each shelf that perhaps some sort of some signage attached to.
