Here are two different Star shotgun mold insualtors. They are named from the fact that the skirts are straight sided resembling a shotgun shell. The one is a nice yellow green. Has one little peck on the base. Great color. The other one is a blue and has a base chip. Has some wire rubbing. I do not know if you can see this well but the top of the pinhole must have had a n air bubble as there is a dipple that rises in to the dome glass. You can put your finer into it. The two for $20 plus shipping cost.
