Hello All! I recently dug this in SF, CA, and am trying to get the correct shape name, and more info. It is 3 1/2" X 2 1/2", has no embossing, one wire groove, and a 1/2" channel from top to bottom (both ends are the same) going all the way through the middle with no inside threads. It looks pressed into a mold, seams on both sides, and one end has little chips where the excess was knocked off. The color is purple, leaning toward puce. I've seen a lot of insulators, but never one in this shape. The site is 1840's through 1890's material. Help me out!
