Possible Sentry or Screamer and Model 2?

[Daniel]

It sounds stationary, so it is probably a 3-phase Sentry or an 8-port Model 5 with an aluminum rotor. There are no eight-port Screamers; they only came in 9 or 9/12.

See Modernmidnight's recent post of a Sentry 5V. It sounds just like this one.

The 5V is the same pitch as the siren in that video, although the 5V's don't wind up that fast. It could actually be 3v8.

I think I might have found the siren via Google StreetView: [Link].

Looks to be an ACA, not seeing the "tubes" coming out of it like a sentry siren.

Edit: Scratch the above - Looks like a model5/7 from a nearer and somewhat more clear angle: [Link]

Just heard the one I recorded the other day go for 5 cycles for a fire today and they sound pretty much the same. I'm guessing its a 5v.

The 5V in Modernmidnights vid doesn't wind up as fast as this siren does. Since a high tone Model 5 or 7 can also be heard, and MD5 said that this siren looks like a 5 or 7, I'm beginning to think that this siren could be a low tone 5 or 7 with a light rotor, like Daniel said, but it could also be a 5V with an unusually fast wind-up.

I looked through quite a bit of that town on Google Streetview and just saw the Model 5/7 we all have seen. Where is this elusive mystery siren?!
