Anyone able to ID this site, it appeared on a Facebook group I’m on?

Only ID is the Air Ministry crown and 1942 (edited as I’m a mong).

Part of a bore sight kit for aircraft guns?

Do you know if there are any other markings (hidden by the paint) such as a sect/ref no?

Nothing, what you see is what you get.
It was sold to the bloke as an air rifle sight but no indication of its real purpose.

The hex nut mounts and the complex reticule suggest that its part of a collimator for some sort of high precision equipment - gunsight, bomb sight etc.

Can't see how it would be a boresight, looks more like a component of theodolite / heliograph / signal lamp to me.

I'm going with part of a boresight or similar. No obvious indicators of it being part of a sight or target acquisition system. Judging by the differential damage/wear it looks like part of a larger assembly.

Perhaps a 'gizzit'' from a broken item taken home for the kids. "Look what my dad brought home from the war."

Maybe from something like this..... or this.

Not with a big hex nut on both ends it's not, with two raised bearing bearing surfaces on the barrel of the sight which appear to be of a slightly smaller radius than the hex nuts:

No, I believe it's a sighting scope of some sort which is clamped by the bearing surfaces onto the frame of another piece of equipment.
