I've added this pic being nobody responded to my original post of this insulator. Click here to see original details [id=310825417]. I've also looked this insulator over and noticed the skirt is curved outward when any I've seen in the past had straight skirts down from the wire groove. The olive swirl in the dome is even darked then my pic. You don't find these everyday. I've also reduced my asking price from $60 to $50 shipped. First email gets this rare one.
