Thanks everyone for your help!! They do look like the ones described by werdna above and I have looked to see whether I could remove the grey colour from the centre - however the grey seems to be the base with the chrome outer edge and 500 logo laid on top.
I thought they may have been American too John 2020 as Fiat UK said they've not sold them but they appear to be genuine Fiat parts. I'll keep looking that side of the pond but there's nothing on eBay USA!
I've found you can chrome plate rigid plastics - you need to copper plate it first then nickel plate it before finally adding the chrome plate - think this may end up being the way to go!
Thank you all again - any more comments greatly appreciated though!
