Well technically they did make more than three sirens. For one, there are at least three different sizes of the Siro-Drone: the tiny 2HP version, which I believe is known as the Type 92, and the larger 5HP version, likewise known as the Type 95. I know there's also a 10HP version, but I've never seen a nameplate for one so I don't know what they called it.
The Sirex I know less about, but I seem to remember that there were some different versions of that one as well. Maybe someone else can elaborate.
The Super Sirex came in single-head with one rotor, single-head with two rotors, and dual-head, but in that case it's all just different variations of the same siren.
As far as I know, those are all the sirens they produced.
