This nice old 2 pc porcelain signal really is a bit different then most. Very crudely done greyish blue tinted glazing with a light sprinkling of cobalt blue spots ranging from a pin point to the size of a small garden pea. These spots are predominantly located on one side of the insulator. There is a heavy "runline" of glaze around the base of the insulator where it ran and accumulated before firing to cure. Insulator is a no name and is mint. $15 + $7.50 shipping.
