So in this video I can sort of hear a Thunderbolt, but the most pronounced sound it a very high pitched clear siren. I'm not sure if it is some sort of electronic, or some sort of weird echo from the Thunderbolt, because they wind down at the exact same time. I'm also not totally sure if it's a Thunderbolt, because the sound stays clear the whole time (from what I hear, anyways) and it doesn't sound like it's rotating.

I'm thinking that it could, in fact, be an actual thunderbolt emitting the sound. I sped a portion of the audio up using Audacity, and it clearly sounds like a 5/6 port Thunderbolt.

Well, of course I hear the T-Bolt, but it doesn't sound like it's rotating.. of course it could have a broken rotator, but how could it possibly be emitting that Nashville ATI sound?

Hate to ruin the fun, but this video is fake.

OOOooohhh. That explains it. Thank you for debunking this.

I want to say that's a little giant but I am not 100% on that.

What even is that? It looks like some sort of Heath or Hedberg siren.

To me it looks like a 550 DHTT or some kind of H.O.R without the long intake cones

Impossible. It is too small. Anyways, I assume that it is a vintage warning siren that had been modified.
