At one time I had a 58 watt siren it was a small silver box with wail & yelp only. It had a very good tone to it. Anyone have one? Unsure of the name but I believe it possibly came from either SASO or Darley.
I had one a long time ago. It had a blue housing with a black faceplate. I'm probably wrong but I want to say it had omni sound on it someplace or I may have dreamed that up...LOL
