Westinghouse go with transformer-sub station. Made of cast aluminum. The six brass insulators unscrew from the transformers and it has a thick enamel finish. 4 inches long and about 3-1/2 inches tall. Front is embossed WESTINGHOUSE and the rear is blank. Looks like a paper weight. Been in my collection for a long time and I have never seen another. Condition is mint. $150.00 gets it and that includes 2 day priority. PayPal, check, or mo is fine. Thanks
