This is a CD 125 No Embossing with {MLOD} and is light blue aqua in color. It was found on the Central of Georgia Railway telegraph line between Fort Valley and Columbus, GA. These were not common, but I did pick up maybe two dozen plus which were traded into the hobby. I'm guessing that this is most likely early Brookfield production. The other Brookfield insulators found on this section of telegraph line included CD 126, 126.1, and 126.3. In addition, there were the standard complement of CD 145 and CD 133 Brookfield's.
