CD 742 MT CO threadless in a nice shade of blue. These are usually pretty beat up on the base. This one has a fingernail size flat flake that takes out the "M" in MT CO, and two ½" chips that remove about 1/16" to 1/8" of an inch of glass. It does have a ½" wide sheer flake from the base up to the bottom of the wire grove. Sounds worse than it is as again these are usually really damage prone insulators. $200 shipped to your door in the continental US. Canada will just be the extra for international. I do have more pics if interested. Color represented in pic is very accurate.
