It's marked as Savoy Circus on a map - well on Streetmap at least...

...is it Western Circus on the signs there then? And more to the
point, where exactly is the purported Circus, or was this location
once host to a long gone roundabout?

Lots of circuses do not contain roundabouts... I'm not sure if they all did
once.

I realise there is a roundabout
of sorts as traffic coming off the westbound A40 that wishes to head
northbound

.... or southbound traffic that wishes to head west...

has to go literally round a block (Old Oak Lane, East Acton
Lane, Oal Oak Common Lane), so is that the Circus?

No, and that's not a roundabout either, because traffic looping around the
north corner has to give way.
