Here I am offering a very nice and tough to find large Italian J ball insulator. I believe these are Pyrex and embossing on the top is HT92 UNEL 38111.The colour is crystal clear. These seem to be fairly uncommon to find and are not listed in the GIFONA book. Only damage to speak of is a thin, small clamshell flake on one edge, a small scratch and a few fleebites. The base is polished where they snipped it and there's a thin flat chip from this polished pontil which seems to have been caused when they polished it. Displays excellent. Please note that the small ball on left is SOLD.More pix on req. First mail to me.... $90 shipped in USA/CANADA, other countries I will assist with shipping.
