This insulator has the large factory rectangular shaped mark up inside the pinhole. It has two light pin-head sized marks on the upper wire ridge, and some very light wire rub in two short areas of the wire groove. There are a couple of tiny flakes on the base bottom/edge, one of them removes the "1" of the patent date, and a tiny open bubble removes part of the "N" of National. The base embossing is light, but readable. There is a 1 1/2" long bruise at the base, another partially open base bubble, and a fully enclosed base bubble. The base bubbles and bruise render a "cloudy" appearance to the base glass, but the embossing is intact. Was $275.00 shipped, Now $240.00 shipped to USA addresses. PayPal No Fee preferred, but would accept MO or personal check if I know you. Thank you for looking.
