I'd guess at least two engravers at work.
One doing up the frame. Lighter cuts. Scroll background removed w/a liner. Scroll leaves occasionally roll over and are shaded to show that effect with a single point graver.

Another that fell in love with the hollow point punch did the bbl and the trigger guard. No rolled over scroll leaves in that guys scroll work. Everything much heavier cut inclu the border. Loves big simplistic oak leaves

Not that it couldn't be the same engraver, but the frame cutting is better quality IMO.
Even engravers that do cut different styles on the same project don't loose their overall degree of skill in changing from one pattern to another.
