That is by far the coolest looking siren I've seen! Thanks for sharing!

Looks like an HOR. If that motor really does run at the rated 3450 RPM, that thing would be insanely high pitched. Could you do a drill or leaf blower wind up or something and take a video?

Here’s one without either of the stators, and one rotor missing.

Thanks for the comments, it will take on a different look once both covers are installed. The motor name plate shows the RPM @ 3600
