Thanks for looking! This is one of many of these great vintage corning glass 12" hurricane lamp clear chimneys. These are all in unused condition, but they have been in storage since the '70's, and there are some fly spots on some of them. The fitter is 2 and 15/16ths inches. The top circumference is 1 and 7/8ths inches, and the width of the widest point is approximately 3.5 inches. The globe is right at 12 inches tall. Thanks again for looking, and be sure to check out the rest of my great items on eBay!
