Here we go again. Re-took some pictures of three CD 106 Gayner's that I found last week. All three have a strange mold mark below the lower wire groove above the 9 of NO. 9. Looks like an oval. . .with a H inside? Am guessing that somehow I managed to find three insulators made from the same mold. . .with the same strange. . . repair? Just for fun. . .I used some calipers and the diameter of the oval is the same diameter as the oval on a CD 106 Lynchburg that I have.

Any thoughts?
