Found it, PDF catalogue third of the way down, described as "number plate hinge system"
silly me not googling that
. Anyway, looks exactly as mine, sorry, my old one.

Their supplier no longer makes them, not enough numbers, well it's hardly suprising considering how well it's been advertised, ffs!
I'm guessing two of us are interested? If they could find another supplier...?
but some people only care about whether it works & not what it looks like. That's why you see fill points in rear quarters, not even colour co-ordinated. Same as some are OK with a towbar modelled on the Forth Bridge, others have detachables.
As said, I have a length of stainless hinge in my garage doing nothing

Thanks Andy, stick our name on it if you don't mind? But as I'm sure we all appreciate, got more enough on with these cars without making number plate brackets, although it looks like it may well come to that.
My personal list of jobs just tripled with another omega to service, convert, irmscher up, fit traffic master, harmen car den, telematics loom, swap interiors about, fit rear blind etc, and that's just on the black car.

should be worth it though
