The rear side of this insulator actually displays best being the milk is thicker. The milk has some black junk mixed in. Don't know the EIN for sure. May or may not be 050 wide wire groove. Just know shape of dome is different from the many, many, many Star CD 162's I've had in the past. Over all the condition is good. Has a flea bite on rear skirt Worst to report is a clam shell base flake on the bases front side left of the star that is somewhat noticible when displaying the front side. I'm adding two more pics of this piece. One of the front view and another showing shape of dome.
