This appears to me to be a CD 106 but I have not been able to locate another example of this insulator. This insulator was picked off the line several years ago during a factory tour in Mexico by a member of my family. He asked if he could have one at some point during the tour and was told by a member of the factory management that it was "forbidden". However, another factory employee slipped it into his coat pocket as he was leaving the factory. Does not make it more valuable but still a cool story. Does it appear in the price guide? Thanks for any help
