This is a CD 147 embossed "Patented" on the front skirt and "Oct 8 th (superscript / underline) 1907" on the back skirt. This specific insulator was found near Albany, GA and is a rich emerald green with amber swirls. The photo was taken with very strong backlighting so that the amber swirls would show. The CD 147 style was a very common insulator found in Georgia on every line I hunted. I had about seven different color and embossing variations in my collection. There were no Hemingray or no embossing units. Although there were some light to medium aqua shades, the colors were mostly dark aqua - almost teal - with a few greens and dark greens. I'm sure I must have passed over many good colors since most of the insulators were heavily sooted and you could not tell what color they were from the ground. I would refer the reader to nice research article which was written by Jim Sinsley (see http://www.insulators.info/articles/CD 147.htm)
