EIN 170 embossing. Periods after CANADIAN, PACIFIC, and RY. Non after CO. Has so much purple swirling around the insulator looks light purple from a distance. Get a good closer look and you'll see the seperation between the purple swirls and the steel gray base color. The condition is near near mint. Has some difficult to notice nibbling at the top of wire grove on the front right side. Only a bit of that nibbling effected the base of the the base of the dome where there is a small flake. There is more of the same type of upper wire groove nibbling starting about 1/4" in front of left side mold line which goes from there maybe just over 1 inch on the rear left side. The rear side base also has a base flake. That starts about 1/2" bihind the right side mold line. It is the clam shell type of flake that is about 3/4" at its longest point. Lastly there is a bubble inside what looks like a bruise on the outer edge of the base. That is about in the center of the rear side. ALll the above sounds much worse the actual. The insulator is actually pretty nice.

Book says 75-100 steel gray and purple swirls. Seen these go for much more then that being auctioned elsewhere.
