Nice HG signal offered in this sale. Smooth based and EID [O1O].I would say this is clear, that's the only non coloured listed but it does have a very slight tinge of shadow grey to it which could be from a little ground in soot that oxalic wouldn't take off. Definately not a crystal clear like the newer Hemingray-19's.Comically large script embossing on front and rear with a tiny letter C on the dome. Overall VNM condition, just a few tiny birdpecks around the wire groove lip, a little light scratches on the domeside and a half moon chip on the inner skirt which you can see a little of in this pic. No other damage on this insulator. More pix on your req. Book is $175 range for clear. First mail to me... $86 shipped in USA/CANADA, other countries I will assist with shipping costs.
