I have this siren that I recently found at my uncles machine shop and trying to find out a little more about it. His shop is located in South Texas at our local shrimp basin. He said he thinks it came off of a navy ship I really don't know but it is possible because we do have a ship salvage yard that has had some famous ships torn down there such as Iwo Jima and others. Any help with this is greatly appreciate. click on link to see pics.
