Here is a super neato insulator. Exceptionally clean clear /aqua 2 tone Hemingray-20.Colour separation is about 30/70 and shows quite well. These 2 tones were created when they had 2 batches of glass in the hopper at the same time and got some of the one mixed in with the other. Almost every one of these 2 tone pieces will have a crack in the glass where the 2 colours meet and this one is no exception, it has an almost invisible ghost crack where green meets clear into the wire groove, this was caused by the 2 types of glass annealing at different hardnesses/rates. Insulator rates at a 9.8 on a scale of 10,it has only 2 flaked drips in the rear and displays perfect, no upgrade really necessary. More pix of any side available. Book on these is $250+. My price...
