Here's a very special Chicago for the specialist.CD 135 diamond groove in a very heavy milky blue. Very crude, lots of bubbles and super heavy, consistent milk thru out the entire insulator. I am nit picking on condition for this. This one is in exceptional condition having only 3 tiny flakelets for damage. Two flakes are on the corner edge of the UWG lip area and are from small BB dings and last flakelet is on dometop resulting from a tiny popped bubble. Base is perfect but I will add that there is a touch of micro nibbling around the corner edge of the base, tiny wire rub in the groove and a fleebite or two in the groove. Absolutely NO chips, cracks or breakage that I can find under close scrutiny. Want more pix? Just mail me please.
