AS I posted in the wrong thread, I'll go again!
ACA Cyclone 125 (The one that's on top of the nickel refinery in Swansea);
Federal Signal DSA4;
Whelen WPS 2800 of some sort (on the same airfield as the DSA);
Castle Castings flood siren with the stator heaters;
Gent 4HP (those massive sirens that produce a B minor chord);
Carter's of Burnley siren, don't know the exact model, but it was big none the less;
Gent 2HP (also tri-tone);
Those French sirens;
Carters siren with chunks of stator missing. Noted to still sound loud and clear despite having a bomb dropped by it when it was sounding.
Various autowailers and telephone relays for the sirens.
