Any comments on these "no embossing" or "Patd" CD 126 designs would be most welcomed. I suspect this beautiful teal blue CD 126 might also be a no embossing Brookfield. The "Patd" came from California and the no embossing teal was found on the Central of Georgia Railway telegraph line South of Fort Valley, Georgia. I will post addition pictures of these insulators.
