I didn't say rare, I said outstanding. You will be hard pressed to find any flaws in this unembossed CD 267 cable insulator. This is another one of those Boston elevated transit system insulators that have been packed away since 1988. This is another of those insulators that beat the demolition crew by just a few days. Clean as a whistle: neat as a pin, sharp as a tack and it looks like a million! Nice blue color, excellent condition, a few neat bubbles; just waiting to join your collection. I'll post a second photo just to show you how great a piece it is. I',m pricing this one at low book of $100 plus actual shipping cost, anywhere in the U.S., not to exceed $10
