Here is a closer look at the insulated chain string with porcelain bushings separating the links which Elton posted [id=460119810] .... and here is the insulating element for this contraption[id=460140507] . A number of these porcelain "bushings" have been floating around for years in collections but no one knew what they were... This historic photo gives them allot more value in my opinion!
