This is a very nice loud electric horn that came from a power plant that was built in the early 40ies. It works very well and will for sure wake up the neighbors. We live in country and tested it out and sure enough the neighbors on both sides of us heard it. It does show some signs of age but it just adds to it's character. Check out the pictures and my rating and you will be able to be assured that you are getting a fine vintage horn as described. It is 21" long over all ,4 5/8" across horn tube, and horn tube is 17 5/8" long. It weighs 7.15#.
