This is a CD 145 W. Brookfield (arched) / 45 Cliff St / N.Y. in deep purple which was found near Americus, GA. It has a dome mould mark of 30. This picture was taken with natural backlight and shows the embossing. However, the color is not as dark as the actual insulator. SCA Brookfield's were found on the Central of Georgia Railway telegraph line between Fort Valley and Albany, GA. There were not a lot of them - probably more than the green's, but there were enough to make for some good trading stock.
