Hi everybody, I recently purchased an old fire siren from a village near my college. It appears to be an 8 port Darley 3v8, but the metal band/label that came with it says it is a Champion. Here are some pictures of it (sorry if the quality isn't too great on some of them), can anybody identify it for me?
