No, It's not the Great Barrier Reef! Still, a nice offering of white porcelain insulators. On the left, a U-152 COOK in mint condition. In the center, a U-143A NN with just a small base crack. And finally, a G.P.Co.(marking inside an oval) U-282B in exceptional shape. Asking $10.00 each plus postage, or take the lot for $25.00 plus shipping. Thanks for lookin' mate!
