That's a horrible pic. You can't even tell if it's a siren or not.
It is most definitely a siren. It is behind the Sinking Valley VFD outside Altoona, PA. I don't have a digital camera other than my cell phone, so that was about the best I could do. I will borrow a camera one of these days and get better pictures.
I have never heard it, but according to friends that live near it, it's single tone. It looks like a stack of plates, covered in rust. In my 10+ years as a siren enthusiast, I have never seen another siren of this type, in pictures or in person.
