Also in the heap of insulators out in the field were four of these glowing silver colored Grand Canyon beehives. Sadly, one had been split into many pieces by being left upturned and having the water freeze inside and break it. But three made it just fine. There was also a light aqua one that was a dead ringer for the WFG CO toll in the heap too. Photo shows the center one still uncleaned, The one on the right is essentially threadless, while the one on the left has a lot of fine fizz and some yellow-amber up around the top of the pinhole and the dome slumps to almost pinch off the wire groove completely. Bummer !
