Here's an insulator that seriously just doesn't find it's way into collections very often.CD 153 GAYNER 48-400 in milky green aqua. I pulled this one down myself about 9 years ago on the rails next to my house. I have only found 2 of these, one I gave to my sister and this one I kept myself. Insulator looks 100X better when seen in person. That odd spot at the corner of the N is actually a small ball of stone inside the glass.
