Not sure if this site has ever been brought up.

Very much looks like Klaxon:

They seem to sell Indian long-range sirens, the Sirenco models. I think that Sirenco is Indian.

Sirenco is an Australian firm, found at www.sirenco.com. I have never heard of hydraulic and pneumatic sirens before. The only Indian siren manufacturer I know of is Kheraj.

Sorry. Yeah, I got mixed up.
The non-electric sirens have some small turbine and gear-differential system inside, though the hydraulic siren also needs an outlet hole.
