Yes, the whole system has been decommissioned as of 2020 and all sirens have been removed. I'll get around to updating the map soon

Amended

Very interesting! I'll get it added in.

Thanks! I'll have a look into the Diageo sirens, no idea where they've gone.

It could also be a Mechtric with a different motor for the UK market? Even if the motor was slightly different, literally everything else matches the styling of the MS22. (edit) Admire this beautiful photoshop and you can see that the actual siren looks nothing like a GP6 - the motor is far too long...

Agreed, I can't see the logic in going through all the effort of making a gp6 look exactly like the mechtric bar the colour. I tried to correct it but it keeps getting changed back

Having too much time on our hands is how this map was started haha, I'll get these added now

Found this in the UK, at a dockyard. It's been a major source of controversy on the UK siren map thread, so I thought I'd come here to see if anyone would be able to identify if it's a screamer or an air vent.

Co-ordinates: 50.37396, -4.22343

After doing a bit of digging, I managed to find a distance recording on facebook of the Clydach Refinery ACA Cyclone from a local. It sounds pretty spooky, to say the least!

Wow, you have been busy

I'll work on getting these added in, thanks for finding these!
