CD 145 G.N.W. TEL. CO. in Royal Purple. Great looking piece that is very dense / heavy, and took a lot of glass to make. Threading appears to drop down pretty low and this is probably adding to the weight of this piece. VNM condition, with the only thing to report a rock plink on the dome that appears to be about 3/16". $85 plus actual postage. I can provide insurance if you wish at cost as well. I package all my insulators very well for shipping. If for some reason you are not satisfied, you can return just pay return shipping. PayPal friend mode or check.
