This is a CD 160 (030) B No 32. These are somewhat difficult to obtain. This particularly insulator is even harder to come by in this color. I would call it a green with amber running throughout. Some might call it yellow green. Whatever, it is a really good color. How many of these have you ever seen? If you are a B collector or CD 160 collector, don't let this opportunity slip away! Other than a small flat base flake, this insulator is in great shape. Email with questions or for additional photos. Price is $55 plus actual shipping costs. Sorry, this insulator has found a new home!
