This is a CD 160 (030) H.G. CO. in blue aqua. You will not have to upgrade this one as it is in excellent condition. As an added bonus, it has a strange raised dot above the front left wire groove which can be seen in the photos. You won't find a better one than this. Email with questions or for additional photos. Price is $35 plus actual shipping costs. Ok, lets reduce to $25 and I'll cover shipping. Sorry, this insulator has found a new home.
