Here is a CD 104 EIN [010] (Dome) [backwards] 4 (F-Skirt) (Arc) NEW ENG. TEL & TEL. / CO. SB in light blue aqua with all kinds of satiny swirls over the whole outer surface, with particular concentrations on the rear skirt as shown as well as striations over the dome. I don't know if this is some type of "sickness" from being buried at some point in its life, or if that's how it came out of the annealing lehr. It reminds me of the milky swirls often seen inside the glass of similar insulators, but this is all on the surface of the glass. There are a few scratches and pecks as well as two small base chips shown and some other areas of base roughness. A unique and interesting addition for the CD 104 or NET&T specialist or the collector of manufacturing anomalies. Asking $12 plus postage. Now $10.
