I am going to guess that the unit in the Facebook ad is a 1980s American model.Hi Len, American version, as in made there or made here for export there? Mine says XLO but generally styling seems newer than the one above, boxier. I don't think I've seen one like above, all I've seen look like mine below. Is the one above an earlier model?

Like I said, the Canadian models had heavier castings and ‘Ex-Cell-O’ cast in the headstock face.
