In the words of Mandy Rice-Davies "He would (say that), wouldn't he?"
Of course, you are now comparing different products. New guns made with CNC machined parts are hand fitted rather than totally hand made. There is less variation from sample to sample.
Best guns of the past were made to the highest possible standards using the skills and materials available at the time. As the ages change, the skills and materials differ slightly. You can see it in the guns if you have the eye to see the subtle differences.
