This Brookie signal is just one massive hunk of glass. I guess Brookfield glass pourer was generous on this one. Very beefy from dome to base and in V NM condition. Some light scuffing around the WG lip area, some small pin pricks and a rub on the OO in name and a very small chip on base's edge under New York. Actual weight of the insulator alone is 1 LB 9 oz..Very heavy! Dome top embossed with an I.First mail to me... $7 + actual shipping.
