CD 121 W.G.M. Co. in a very pretty lavender purple. Has some olive swirling in the glass that starts at the "W" and goes up into the dome and swirls around a bit. I have handled a number of CD 121 W.G.M. Co. insulators but haven't seen any with any olive swirling in them. A few little base flakes on the sharp outer edge which is so common and a very tiny wire groove ping on the back. The ones without any swirling in the same condition go for $40 - $45+ on eBay. This one has nice swirls and some dome glass. Price $55.00 plus shipping based on zip code.
