This is a CD 160 (020) H. G. CO. in blue aqua and in vnm condition. These seem to be harder and harder to come by in the last several years. It has a small open bubble on the base with minor chipping around it. This can be seen in the photo on the left side. Regardless, this one would be hard to upgrade! Email with any questions or for additional photos. Price is $30 plus actual shipping costs. Ok, lets reduce to $20 and I'll cover shipping. Sorry, this insulator has found a new home.
