Apparently they're off a 2011 car. I got them as a job lot on an eBay auction, collected them in a filthy state, cleaned them up and they're ok - just ok, not pristine by any means, but fine as spares.
One of them had a fair bit of inner wheel corrosion. Although it was only surface, not structural, it was ugly, so I've sanded it down and started the re-painting process...
The other two aren't badly corroded inside - they're actually better than some of the wheels on my car!
