Hey guys, haven’t posted here in awhile still alive, I recently made a trip out to a small town called Quairading in Western Australia and I found out that they have a potentially active Elektror S4A at the volunteer fire station, does anybody have an idea how old it is?

The siren on the red pole is a Grifco 888, they are about the size of an American model 2

That's an Elektror S4a, indeed !

From shape similar looking like the better known E57 (L52 / L141) siren,
but smaller in size, weight and power (2,2 kW instead of 5 kW).

And - having 12 instead of 9 ports, so a higher tone frequency of
about 550 Hz.

Don't know if the S4a was built in or before WW II. Maybe it is
from the 50s or 60s ?

Greetings,
