Here is a dry process porcelain CPR beehive with uneven whiteish glaze with brown speckles gradually shading towards one side. The real curiosity is the crazy glaze crazing all the way around the insulator, outside as well as in. It's been highlighted over many years of use in a black soot environment. And this is after a long soak in oxalic acid. Besides the crazing, condition is about mint. Add this unique beauty to your railroad/porcelain/Canadian shelf for just $15 plus postage. (No PayPal.)
