I just pulled this out of the box, it's been there for many, many years. I am not sure of the exact color, but it's the only one that is this color out of a 250 ponies collection I have. The book has a value of $400-$500. I won't use the word MINT, so let's call it VVVVVVNM. My asking price is $350.00, which includes shipping in the States. I will provide additional pictures on request. I just received a couple of comments about the color of this insulator. The consensus is, that it's an Olive Mustard Yellow.
