Nice unlisted 728 in really decent shape. Next to the 1/2" bubble is a 3/4" X 1/2" chip. Their is a 1/2" stress line going up from the base, and the base, on the outer edge has a 1/4" flake along with other nibbling. Couple of other pinhead nicks just to be throrough. Insulator looks great, pretty much clean. Picture 2 shows the base. I'm asking $200.00 shipped. First email as usual. $175.00 SHIPPED
