This insulator is a CD 104 Wm. Brookfield / New York in a beautiful Yellow-Olive-Green. It was found on the Central Georgia Railway line between Macon, GA and Albany, GA in the late 1960's. I speculate that it must have been a replacement insulator since it is one of a kind. The photo color is lighter than the actual insulator which is a striking glowing color. Note - this is a {MLOD} with no letters or numbers.
