I have a set of 20s that I took off my A8L when I 'upgraded' to the classic FE multi-spoke wheels. No tyres though.

The wheels suffered from lacquer degradation so there's a spidery pattern on most of the wheels. I didn't get them refurbished as I wanted to spend the money buying the classic FE wheels.
If you're interested, I can supply photos. There are some in my gallery when the car was shod with those wheels. I'm not after much money so make me a reasonable offer.
