There's some really in-depth, informative videos on YT about the hemi air raid sirens.
I went down that rabbit hole a while back. Fascinating and cool stuff!

Spend some time looking over this site if this interested you.
Awesome stuff and history about it.
4 mile range!
Lots of photos and information on the menu on right off page. You could spend a couple hours there easily.

Restored one, took the photo's at the WP Chrysler Historical Museum in Detroit several years ago.

I guess it was December 2012 right before they closed the museum down.
