Although it does have some similar features to a Castle Castings siren, due to the overall look of the siren I’d say that it is a Secomak of some kind (I can’t remember the exact model).
I'm 99% sure it's not a Secomak as it doesn't have chamfered (angled) stator holes, which Secomaks almost universally do. This narrows it down to CC or Carter, as it quite clearly isn't a Gent

I say this because the base of the siren is not curved like a Castle Castings, but rather more angular, like a Secomak. The wire junction boxes also seem to be situated at an angle to each other, similarly to a Secomak.
Earlier Castles also had squared bases. Could be a Carter, but pretty sure they always had centralised motor junction boxes, which this one doesn't. That said, there aren't many Carters left to use as a reference, so don't quote me on that.
The thing that makes me doubt myself is that it doesn't have the stereotypical "giant" rotor bolts that CCs often do, instead having the flatter bolts as you'd see on Carters. Heater junction boxes are only angled/pointing upwards because the museum/whoever restored the siren refitted them at a funky angle!

The wire junction boxes also seem to be situated at an angle to each other, similarly to a Secomak. The only thing that may be confusing is the lack of the word ‘Secomak’ on the heater, however if it is a Secomak I’d probably go with the theory that they had to replace the heater and didn’t bother adding the wording onto the new component.
FYI, the Secomak-lettered "heaters" you refer to were just end plates - to protect the rotor sides - and didn't have heating capabilities. Heaters typically didn't have letters on, no matter what they were attached to, as they were (to my knowledge) a standardised component that could fit numerous models of siren.
So it's either a Carter with a very late-production motor, or a CC with different rotor bolts. I could go and forensically analyse the rotor vanes for further clues, but a lack of reference photos may hamper that!

No, the Klaxon SS6 is not a Sentry 95...
