Here's a nice medium purple R. Good Jr. toll CD 121 insulator in vnm condition. This insulator has a tiny rear base flake and three half inch shallow annealing lines up from the base, one in front below the first "O" in "COLO.", the second is at the right (insulator's left) mold line to the rear and the third below the "16" on the rear. Annealing arc next to insulator's left mold line as well, associated with the one I mentioned earlier. Part of the manufacturing process no doubt and noticeable only if you're looking for it. VNM display. Otherwise, this piece looks to be in as-made condition. Nice bubbles. I first offered this at $225 shipped. This week, I'm offering this at $175 shipped. C'mon! You gotta love the large, crisp embossing and the beautiful medium amethyst color! And this is part of mountain west history! First email takes this nice Denver toll!
