Here's a rare & Tiny 1 3/8" clear radio strain embossed "PYREX" on the nose. One of only 2 known. Probably made by Pyrex Italia as it was used in service there (Italy). VNM shape with a very teeny slice in one groove and slight roughness on another groove, and tiny area on both ends (factory buffed on one end) and not sure if molding flaw on other end. For 2nd view/close-up [id=254359755]

First email gets this cool piece for only $125 postpaid. Thanks!
