Here's a rarely seen unmarked no-tie composition insulator featuring standard British threads (complete with original hemp used for securing the pin). Not rubber or plastic. Weighs approximately 2 pounds. A few small base flakes and wire rubs on one of the wire slots and inner skirt break [id=363057940]. Only about 6 known.

First email to say they want to buy it gets it. Actual postage calculated to outside USA. Thanks!
