Dug this out of the bed of an old bucket truck the other day. How many of you know what it is? I figure the rest of us line hands out there will know right off the bat, but for those of you not in line work, what is it? Used to see these all the time, but they have pretty much been replaced by poly or a composite material (instead of the porcelain). No manufacturer ID anywhere on this. [id=86643426] to see next photo
