Thanks Dave and that grading system is very similar to what LC Smith used. We may come to a dead end trying to put specific names on gunmaker's damascus patterns. As the 76' AR article makes clear, there were many grades of Bernard, Boston, Oxford, 'Crolle', etc. AND different barrel makers, with different patterns, using the same name ('Bernard', etc.)
