This group of insulators include an unembossed blue O-B on the left, a Victor (V in a rectangle) dark cobalt hightop in the middle and a light gray O-B cable on the left. All VNM or better. How about $15 for the blue unmarked O-B, $20 for the V hightop and $5 for the gray O-B. Plus shipping for any of them. $35 for the lot. Email with any questions. Thanks!
