Good knowledge. Thank you!The wring that originally went with those insulators on the wall bracket would have needed an earth wire exactly like the one in your pic.
I removed the last traces of ours when I re roofed and upgraded the porch last summer.
The earth wire would have gone into a rectangular Bakelite box mounted where your BT master is now.
