so I'm quite sure this isn't a Screamer.

I was just saying they sound alike

Anyway listen to the windup. There was a couple HOR models that sounded like that.

The windup/down speed of any siren has to do with the weight and air resistance of the motor versus the torque of the motor. Compare an old steel-rotor Model 5 with a newer aluminum-rotor version.
