Here is a much closer view of these cobalt blue neutral phase marking insulators. Really nice combination of porcelain styles! Pictured from back to front is a large 4" dark blue OB pineapple type spool, Cobalt blue 6" marked Victor Insulator Company dead end strain, two cobalt blue U-663 OB pin types and a very dark cobalt blue almost black glazed 6" dead end strain marked ITE with a 1962 date marking. SWEET!
