The Haunting RAVENSTRUTHER SIREN TEST! IT'S LOUD!! (Best ever siren video!)

This BEATS THEM ALL - I've filmed lots of sirens from the Broadmoor system, but this one.... I'm almost speechless! So it's probably easier if you just watch the video (oh.... and it would certainly help if you have an interest with old sirens!)
..........
BTW, the pronouciation of "RAV-EN-STRU-THER" - nope!!! According to youtube user 'cgiof3ln' it's pronounced "Renstree" or "Reinstree". ...I mean, that would have been my second guess!? (sarcasm!)

THE MRMATTANDMRCHAY CHANNEL, established 2009:
I'm passionate about uploading quality and interesting videos for YOU, my audience.
What is my channel about? "Old lift machinery made interesting", old air-raid sirens, prehistoric alarm equipment - things that I find fascinating and I hope you will too. If "I" don't find it interesting - IT DOESN'T GET UPLOADED!
I always spend a lot of time editing my videos with animations, video in-sync with music and voice overs to make them this way. I'm also a perfectionist!
My moto - "Quality NOT Quantity" - spending a month editing a video is not a rarity!
But without you, I'm nothing here. Thank you so much for watching.
...mrmattandmrchay is me (Matt) and my son Chay.
