Here are a couple of nice blue aqua insulators with fine olive swooshes to set them apart from the rest. The CD 104 is EIN [030] (F-Skirt) (Arc) NEW ENG TEL & TEL. / CO. SB. There is a 1½" vertical stress fracture at the rear wire groove, wire rubs, and a few scattered pings. The CD 121 is EIN [010] (Dome) [Backwards] 4 (F-Skirt) AM.TEL & TEL Co SB. You can see the dome ding, and there are a couple of other insignificant surface scratches mentioned for accuracy. Inquiries welcome.
