CD-133 H.G. Co / Patent May 2 1883 - Front & Standard - Back in Yellow-Green with sharp DP's. I wanted to contrast the color with the CD 145 H.G. Co. - & Front Petticoat - Back in a lemonade color. The CD 145 H.G. Co. were found on the Central of Georgia telegraph near Albany, GA. I've posted this insulator a few years ago [80753224] so the reader can get information about these insulators from the earlier post. Most of these insulators are loaded with pot stones and look like what I called "uranium" glass.
