I have a set of Dunlop 72 spoke chromed wheels No; XA472. They look original early 60s looking at the chrome(it, s very deep not silvery)which stiil covers about 80% of the wheels. Is it possible to restore the areas covered in surface rust so I don, t need to re-chrome as they never look as good. Also could you tell me if the rim code identifies them as original. Many thanks. Mark.
