Actually, Kimber did make a Super Grade. The early versions were stocked by Bishop, Fisher and in-house by Kimber. I actually own SG38 in my collection. You can reference Eaton's "Kimber Collectors and Enthusiasts Manual" for pictures and serial number ranges. Also in 1989 they replaced the Super America for one year with a high end rifle called the Super Grade and I have an example in my collection as well. I have never heard that Winchester had trademarked the term "Super Grade." Do you have a source for that?
They also made other very high end rifles like the Custom Match, the 10th Anniversary and the Centennial.
