There's a scale on the underside going 'backwards'.....although you may get a crick in the neck trying to read it. The small challenge involved was to make sure that both scales accurately centre on the central pin gnomon with both noon lines truly co-planar. It actually took twice as long to make the octagonal presentation casket in black walnut for this item as it took to make the metal parts of the dial. Tony M.
