These insulators hale from Florida where they were extensively used on the telephone and electric lines. These are extremely soft glass that was easily etched and damaged by the acidic soils. This one is no different, it has the etching so prevalent of these and is a medium opal colour. This one has 2 chips on the rear WG side, one's about an inch and the other is a lot smaller. Insulator displays excellent from HEMINGRAY side. Book is around $175. If you cannot afford a mint one but would like this hole filled, this one will do it at $58 delivered. More pix available on request.
