Here is a toughie. The top is blue. Bottom isn't quite as blue which is why I say maybe blue aqua. It's in great shape. Top has a 1/2" x 1/8" open bubble along the inside base edge. A 1/4" scratch line at the base of the threading going up. And one little pinhead nick. Some neat surface lines on the skirt. Bottom has the typical top of the pinhole nibbles and their are some stress cracks in the threading. A 1/8" open bubble at the skirt/base edge. One flea bite on the crown area. The value guide is underrated for this piece in my opinion. Don't see these as much as the other prism insulators. Blue $125-150. Considering the pinhole issues thread stress cracks and not seeing these very much, I'm gonna ask $140.00 shipped. 1st email as usual and thanks for looking. Email me if you would like more photo's.
