I had found this insulator (B) in my mom's friends basement and had heard that this style or CD is pretty rare, the color is pretty exact in the picture, the color is an apple greenish color and has a nice amber swirl in the dome. I was just wondering what the CD # is on this piece and what each of the colors, or at least the color of this one is worth!!! I was informed a good while ago the CD # and that apple green for this one is worth $1,000-1250 ...True??? All help is appreciated! Thanks
