Wanted Campagnolo Carbon record 10sp Grey 52/53 T chain ring

[Sir Walter]

Hi Guy, recently bought a 10sp Record equipped De Rosa with the carbon chainset, unfortunately previous owner had the big ring swapped out for a 50T ring in silver, more annoying is the little chain saver pip does not sit behind the crank as it should do. So I am looking to rectify this, these original rings are annodised light grey not shiny silver or black.
Hope someone can help relive my OCD with this. Thanks.
