That is a tough one. The difference in color between the hinge plate and the floorplate is normal; I have never saw them match, but the wear on the floorplate just doesn't match with the rest of the gun. It may just be lighting or was just a bad job from the get go??? It may have come from the factory mismatched with a steel floorplate and the owner put an aluminum one on it? It is usally the other way around though, aluminum SG plate on a Standard or African?? Who knows. I think it is a true Super Grade not a parts gun. If those things could talk.
