Will you be explaining the stamped numbers and letters as well? I found 3 more rims in the boot of an XF out at the farm the other day ( god knows why I put them in there). The piles getting sizeable so I'd like to sort out whats what soon. I've got one set that definately looks like some kind of knock off copy, flakey chrome, crappy centre caps. Do you know what these were? I think the brand on the centre cap is Knights or something like that, haven't looked at them for ages.
