You too can learn to clean insulators like "The Master" ! --- Here's a trio of dirty, cruddy CD 138 Brookfield/Postal Tel. Co. pieces that I rescued from a farm 150 miles north of me last Saturday. I can see decent embossing on them and one has a 1 on rear dome. Pretty good condition as far as I can see with some base flakes and one has a rear skirt scallop. NO JUNK HERE. If I clean these I'll get over twice as much than what I'm asking now ! I have enough to clean so I'm lettin' some lucky ICONer do it for $28.00 + shipping. First email that says' "I'll take it.". No PayPal. Email with questions.
