A long story short, I had the mirror/reflectors replated in my late grandmothers car's headlights because new ones were too expensive- it was a 1981 car.
Somehow, it was recommended to contact a company in Brisbane Australia. They plated pieces for the funeral industry- all the bits which go on th casket etc. Hyqual is their name.

Anyway, a phone call later, they were packed up and send off. They came back and are WONDERFUL!!! This was approx 10 years ago and they are still excellent, shiny and throw a decent coloured light.
I intended (great plans he has....) to send the reflectors up from my jeep headlights to them, but haven't gotten around to it. Oddly i was only thinking about this today that I should dig them out and send up!
I assume there would be a similar plating place in the UK you could send them to? Just a thought and hope it helps.
Cheers,
Ian.
