Can you categorize engraving by each individual engraver or are there various schools of engraving? For example, on a Thomas Boss can you see a difference between the Rose and Scroll or Bouquet and Scroll engraving over the many centuries that a Boss has been built or has it pretty much been the standardized? And so much the same that the Rose and Scroll engraving on a Boss can be differentiated between let's say a Holland & Holland or a James Purdey Rose and Scroll or Bouquet and Scroll engraving?
All the best
