Dial-A-Pattern Depression Glass Wheel

You know, I'm surprised this beat-up thing isn't older than 1970, when it was printed. This wheel is 11 inches across and it pretty sorry shape. It's from the "Connoisseur Series". Fancy. This wheel has information on both sides.

So, you dial the pattern you see, I guess, and it tells you the colors it came in along with the name. I wish I knew what Clevco was and what happened to it. I googled "clevco northridge" and got The American Kennel Gazette and Stud Book. That would make a good wheel, wouldn't it?
