Want just one threadless in your collection? Something you can show what a real early insulator looked like. And you don`t really want to spend a ton of money. Consider this CD 734 McMICKING. There is a 1 1/2" inside the base chip (some of it right behind the McMicking embossing).There is one small chip on the upper ridge of the wire groove. Not all that bad for an insulator that`s probably 140 years old. I would think it should sell fairly fast considering my price of $40 plus shipping. That`s right.....$35 gets it delivered to your door.
