Well, this electrical arc that is emblazoned down the skirt of this CREB blobtop certainly gives this guy a lot of character! Nice blue aqua 55 Fulton St that has a wide,2.5" long arc mark etched down into the surface of the glass where the errant current crossed to ground. I had tried to remove this thinking it was sickness, but upon very close inspection you can see that the glass surface itself is micro alligatored where the heat lightly melted and blistered the surface. There is another smaller arc burn aboutan inch to the left of this too. These arcs start at the edge of the wiregroove and down to the base where it would have either crossed to the pin or the crossarm. Insulator is VVNM, a few tiny fleebites and a small rub or two in the WG trough. No dome /shop number. First mail to me.... $15 + actual shipping.
