Here we have a steel porcelain sign from our friends at Pennsylvania Transformer of Canonsburg, PA. U.S.A. I was pleased to discover that they are still making transformers in Canonsburg under the name Pennsylvania Transformer Technology. If you go to their website at http://www.patransformer.com/index.html you can see they are still using a larger version of this logo on their products with the word Technology added. This sign measures 10" in diameter and is in excellent condition. The only flaw is a chip on the edge between the letters V and A with some rust, it is visible in the photo. Your cost is $30 and that includes shipping.
