Last of the glass J balls I have in the large size. This one, like the last 2 are suspected Pyrex. The colour is a really pretty golden straw with excellent glass clarity. The ball has been used and has 3 shallow clamshell type chips on the corner edges of the grooves, some light rub marks, a small almost invisible bruise on the corner of the groove, light stress marks in the wire thru holes where the main tension was and some various tiny flakelets and fleebites. Not perfectly mint but displays VVNM from the one side. Not listed in the GIFONA so I cannot give you book values, but they are not super common. More photos on req. Return privileges on all my insulators if not satisfied. First mail to me... $50 + actual shipping.
