I picked up this group at a couple of junk shops in my area. On the left is the upper portion of a Holmes tree bracket with a cracked Blue Aqua CD 160 Brookfield. In the middle is a beautiful Blue CD 104 NET&T with nice dome glass, and on the right is a Sky Blue W.C. Shinn Mfg. Co. lightning rod ball in remarkable condition. I'll have these with me at the Yankee Pole Cat Insulator Club show on Sunday.
