An old pole still standing with wishbone bracket and insulators that was 1st transmission power line to old cotton mill in my town of Simpsonville SC.. I'm not sure of the M number for them.. I think it was from 1914 or earlier time frame.. I been trying for a few years to get these and hopefully I will at right time from some linemen.. There is 2 other poles like this but no insulators on 1 pole and other pole still has 1 insulator on pole.. That is the static wire in the photo and has fallen over..
