Here are two of my favorite insulators! The CD 126.4 was a recent aquisition from the eBay seller sarcliffhanger! This little guy has what appears to be a small tack nail! Thanks again sarcliffhanger for this wonderful insulator! The CD 126 was aquired last year from a local bottle digger. He said he had some insulators he wanted to get rid of. $50 and 80 Blobtops later I found this! The Blobtop has a metal flake that was embedded in the glass.
