CD 112 S.B.T.& T.CO. Ice Blue This CD 112, also known as a "Keg" style insulator, was manufctured for the Southern Bell Telephone and Telegraph Company in the early part of the last century. Several different glass houses made insulators for S.B.T.& T., including Hemingray, who probably made those embossed between the wire grooves. This insulator was removed from an abondoned rural telephone line in Monroe county. |
