I'm not totally sure on this CD number. I am going by information from one of Ray K's old auction catalogs which indicate that the pictures in John and Carol's Insulator book for the CD 732 and CD 731.3 were mixed up. I would like to say that I found this insulator in Georgia, but that is not the case. I purchased this one from a gentleman in South Carolina. It was said that it came off a railway telegraph line which came out of Georgia and ran into South Carolina. That's about as much as I know about it. I am including it in the Georgia information as I did find a threadless shard on the line from Fort Valley, GA to Columbus, GA which could be a good match for this insulator.
