Call me optimistic but I think there will always be a demand and a market for those highly skilled in the craft of firearms engraving, as in any trade. History is full of examples not only in weaponry but painting, architecture, carpentry, jewelry, etc.... granted, there are periods of highs and lows in the markets and maybe not worth a lot until there in a museum or private collection. Still, if it's exceptional work and or a rare piece those that can excel can still can do well and sometimes very well. People that are smart see the value in high quality skilled work no matter what it is. The masses may run to spend their money on trinkets that are made in volumes but there is and always will be people that understand the value of things that have meaning and worth, it is human nature. It's the same reason why people want to drive a Bugatti, Aston Martin, Lamborghini, or Ferrari as compared to a Mustang.
