This is another of my specialties and a duplicate to the one in my collection. It is EIM [030] with non-segmented threads, the word INSULATOR spelled out and a smooth DOME. The color is a typical light blue aqua, perhaps a little darker than some. The condition is pretty good for one of these but it does have a couple of chips, one 3/8" on the lowest wire groove ring and one 1/2" on the next ring up. They are both on the same side so the piece display MINT from one side. There are also two very teeny, tiny pings on that same side. The base is perfect. I am asking $75.00 or perhaps will consider a trade. (See additional picture)
