This is a CD 145 W. Brookfield (arched) / 45 Cliff St / N.Y. on front dome and Pat / Jan. 25th 1870 and the back dome in medium lavender which was found near Leesburg, GA. It has a no dome mould mark. I was asked by several people to post another picture of this insulator. I have a taken a large number of pictures and have selected the above photo. The Brookfield SCA insulators are very hard to photograph and this is the picture I think is the best.
