Here's a very nice unembossed CD 310 Aqua glass sleeve insulator that goes with your coolie hat or muncie type insulator. This comes in excellent condition with 1 very tiny base flake and 1 tiny base open bubble and no cracks with a slight surface haze. Has several seed bubbles for added character. If you already have the top here's your chance to complete your set.

First email gets it for only $40 plus shipping. Thanks!
