The Most Unusual Looking Sirens

Does anyone know what the port ratio of the gents syren is? I’m trying to make a 3d model of it in an easy to us 3d modeling software known as tinkercad.

Well since this thread was brought back to life, I agree that the Allertor is one of the weirdest looking sirens. It always reminded me of a toilet mounted sideways on a pole.

Up there with the Allertor is that rotating Canadian CLM siren. It looks similar to the Allertor, but it's like a Sterling M-5 but with directional horns on both stators facing one direction instead of one "horn" actually being an air intake.

Other sirens I consider unique are:

- The Thunderbolt 1003 with those "ears" on either side of the horn's neck holding the tone solenoids

- The Thunderbeam - really, a rotating slanted disk deflecting sound from the stator above it, truly a unique way of making a directional siren!

- The Hurricane with the horn that splits from its opening to each of the stator openings on the siren.

This comes from someone who lives where the most prevalent sirens are Model 2s, 5s, and STH-10s, with a smattering of single and dual-tone Sterling M-5s and M-10s.
