Actually on the survey disc that Clayton gave us. I only saw one. It's the gray Tbolt on Ellison off of Linwood in Mt. Lookout.
There's one on a pole on Sutton Avenue in Anderson Township as well. There are more than two, but only two photos showing them on the survey disc. If you look through the database, you'll see several listed as "TC4-1000" or "TC-1000" (depending on which table you look at) from 1950.
