Here's a tough Deep Olive Green CD 666 embossed ISOREX (front) 245 (reverse). Excellent condition with 5 micro tic marks, 1/2 tiny ping, light factory mold line grind marks and a small scratch. Easy VNM. Haven't seen one offered for sale in a long time.

First email gets this early glass one armed insulator from France for only $100 shipped. Thanks!
