Here are two English porcelain insulators. I think They are similar yet different. The one has F.B. 40 on the top, the other KP 56. The fb has one hole drilled in the top. The kp has 2 holes. They are therefore altered into salt and pepper shakers. A nice addition for the Thanksgiving table. I didn't drill the holes, that's how I found them The bottoms have big red plastic caps. Asking $20 plus priority medium flat rate box.
