Here's a rather scarce CD 121 AM TEL&TEL Co- insulator made by Sterling (has the Sterling ring inside the top of the pinhole.) This beefy toll has the largest embossing known for AM TEL insulators and this example has very bold embossing to boot! Comes with an unusual raised dash after the "Co". This is only the 2nd example I have found in over 30 years of collecting. Insulator is easily VNM condition.

Has a tiny dome sliver/tic mark and light upper wire groove nick beside a tiny nibble and a very tiny tic mark below the A in the prismic embossing. (Click photos to enlarge details). 2 very tiny pings size of a tic on the left mold line. Very tiny flake on the "L" in the embossing. A few factory annealing lines on the base that are not damage (similar to denver and california insulators). See additional photos posted.

First email gets this scarce toll for only $75 plus shipping. Will be securely wrapped for shipping and arrive before Christmas if you order soon. Thanks!
