No one precisely knows anything about those E.D. Bullard sirens, we know they have conical rotor/stators and are usually omnidirectional (there is a rotational model confirmed to exist, and coincidentally I was the one who identified it as such, because of the rotor shape alone) and single tone (so far no dual tone units are known to exist.
That's about it.
