During the period between 1969 to 1971, I made several trips to hunt insulators on the Central of Georgia Railway telegraph line North from Macon, Georgia to Athens, Georgia. My favorite section was between Godfrey, GA to Madison, GA. My notes indicate the line had four tiers of insulators which were mostly common types including aqua CD 145 W. Brook, CD 145 B, CD 133 /134 W. Brookfield insulators. Although, this was a typical Western Union telegraph line there were no CD 127, CD 127.1 or CD 126.3 insulators - only CD 126 dome embossed Brookfield's. The unique insulators in this section also included: three new signals that were not in my collection. This was the third unique signal style insulators. The exact embossing on this signal is as follows:

CD133.3 Bar and Reverse 3 (Front) & Bar (Reverse) Greenish-Teal-Green with some cull stones and milk.

When I found these, my first thought was this might be a previously un-described King City Glass Co. insulator. I found seven and traded six into the hobby. The one I kept for my collection was put into a box and was not taken out until a week ago. I did a quick ICON search and found out that there were a number of these in the hobby and that they actually have their own CD number. The following are two of the many posts.

Dwayne Anthony has the best picture post of this CD 133.3 - see [216850281]

Roger Poole has the post with the most humor - he calls this insulator "shorty" - see [407004942]

An interesting note: Roger Poole indicated he obtained his CD 133.3 from the Charles Brandon collection. I actually traded my last CD 133.3 to Charles Brandon some time in the early 2000's for a beautiful milky green CD 132 Patent Dec. 19 -1871. I will post additional pictures which show the CD 133.3 back and compare this insulator versus the two other unique signals I found on this same line.
