Probably the best insulator I personally ever took off a line. I found several in the 70's. So it has always held a special place. Thsi one is embossed on the dome "PLW". There is the "B" on the skirt. I would call her mint. Shipping within the Continental US add $8.00 / Canada add $12.00. Has a nice elongated air bubble on the dome. Dark aqua. Sale price: $45.00. Photo taken in incandescent lighting so sorry about not being a better photo.
