Does anyone know the model name or number for the 2001 Roundback? Someone told me it is 2001-AB. Hopefully Adam Pollak can jump in with that, as he photographed a round back 2001 in West Memphis, AR. http://www.jmarcoz.com/sirens/westmemphis3_ar.jpg Hopefully he still has the high resolution origin...

Go with the ASC T-135, we don't have videos of it yet.

I've actually heard some Whelens do that before, in another video. I'll have to find the link.

That's funny how the YouTube poster called them a UFO! Do you have any idea why they keep restarting at random, without winding down? It doesn't sound like a Whoop signal to me.
