Air raid siren - Blitz and Civil Defense full speed indoors - insane

This is a late British Cold War siren made by Castle Castings.

These have 415 volt three phase electric motors, but by using a modified inverter I can run these from a 240 v single phase domectic socket.

The siren produces about 135 decibels....!

If you are intertested in owning one, please contact me at paul.j.lawrence@hotmail.com . I live in the UK but am prepared to ship at cost.
