Thqt is correct. The current repros comes painted in the correct colors. Some of the early repros just came in raw black plastic. Similar to this. What color is the underlying plastic on the repro you have?
I think that is a '71 grille that was sold thru GSCA a number of years ago. I remember that they were made in France (??) I think it doesn't come with studs and you have to paint it. Also, I remember people were complaining that they didn't have a lot of integrity regarding strength.
