Thanks! It's nice to see an original CLM control unit intact. These controllers have a feature where you could have the siren idle at around 60 to 75 rpm to keep the motor from freezing up in the wintertime which is what that knob that points to 60 RPM means. I can't wait to see this siren all resto...
