I thought we all thought it was a cluster of three Model As/Ls/Ds.

wheres the intakes. Thoughts?

EDIT: i just saw the video again and the windown is WAY to long to be a A/D/L because i own an A and L which is a 4 second windown from the type of motor and size of rotor. I could be wrong though!

This siren has stumped us all. None of it makes any sense.

I thought we reached the consensus that these are early electronic sirens with a STH-10 sound chip.

It was an idea, but its not a recording (and definitely not one of an STH10). In fact, they probably aren't even speakers, due to the lack or a re-entrant cone. They look like vibratory horns

Look they updated the video and now it says

ATTETION EVERYONE: BREAKTHROUGH------------ i SPOKE THE THE DES AND HE TOLD ME THIS SIREN IS NOT IN USE. THE SIREN YOU AND I ARE HEARING IS AN STH-10! EVERYONE WHO MENTIONED THE 3 INDEPENDANT MOTOR ISSUE WERE RIGHT. THIS SIREN MAY BE REACTIVATED IF THEY TRANFER IT TO SOUTHGATE, WHICH IS A SUBURB OF MILES CITY. IF IT GETS MOVED I WILL POST A VIDEO OF IT! THANK YOU FOR WATCHING!

That makes perfect sense! Although that is a sickly STH10 they have IMO.

That would explain the familiar sound. Sickly but familiar :D
