Old cast iron bracket with a typical Brookfield dark aqua signal on it, CD 164. They do both come apart. The bracket is one piece not the newer version with the spring threads. I didn't clean the insulator. But the bracket got a bath in rust remover so it's a little cleaner than this photo. I'll leave any other finishing up to the buyer. $15 plus shipping. First email. PayPal or check if icon member. Other bracket poking into cropped picture is sold.
