Hi,
Goo, you are doing very well. Nice job. I cannot remember where I heard this story so I cannot verify it. In England the traditional firearm engraving was done by hammer and chisel from the 1600s - 1800s. It was deep and bold. During the 1830s or so many of those engravers were drawn to copperplate engraving with hand pushed gravers used in the fast growing trade of lithography, which paid more. As a result, gun engravers with hammer and chisel became hard to find and I am sure demanded more for their work. The gun trade adapted by employing more hand engraver trained workers and changing their designs from deep bold engraving to lighter more precise scroll work, which became what we call "English scroll".
