INS-1 WFG Light Aqua & ICE AQUA OR Off Clear THIS AUCTION IS FOR BOTH INSULATORS LEFT: Nice light aqua WFG with an amazing 2 inch long stretch bubble. The bubble starts at the right side of "16" and goes almost to the "D" in Denver. I have had this one for several years and enjoyed the character. The bubble and other glass swirls gives the entire base a swirl effect. The only damage is an eraser size chip to the wire groove above the 16.

RIGHT: Ice Aqua to Off Clear WFG. In the sunlight or in a window this insulator looks gray, or off clear. You can see in the light box it has a little more color to it. It is lighter than the light aqua, but tough to call exactly where it lies.

Neither of these insulators have the surface annealing marks that are common in Denver glass. $35 plus shipping for the pair.
