I just got these from my connection (lineman) at Detroit Public Lighting. From left to right the insulators are the following: CD 295 134 125 164 155 Blue porcelain fire singles. Of the CD 125's two are the Pat 1871(the two right ones, in the front row). I still think it's great that I find these, let alone that they were probably in service only a month ago. I also got a free linemen bag out of the deal, he used them to carry the insulators.
