I personally believe that the engraver responsible for the wild life scenes on Excellentias, Premiers, etc was probably James Charles Scott, or at least someone apprenticed to him. I've read accounts that J.C. Scott was a avid naturalist and had a passion for engraving fowl.

I think Albert Brown (A.A. Brown & son) would've been too young to engrave guns in the 1880's, his father Joe Brown might have had a hand in some of these guns, I believe Joe was the instructor at the engraving school. Both Joe and Albert had a talent for carving deep relief oak and ivy fences.
