I think many "modern" people look at work like this and believe it to be impossible without CNC machinery, elves, or space aliens. I believe "artistry" is a word too lightly used these days. I'm not a gun builder, but I imagine this puts the hurt of humility on many contemporary "artisans" who start with manufactured barrels, locks, triggers, precarves, and furniture. They might be termed "assemblers." And I'm not trying to take anything away from those who make well constructed arms.
While viewing this thread a comparison came to me. I was thinking about making a fine boxwood baroque recorder with powered lathe and drillpress, as opposed to entirely handmaking a Boehm system flute in gold. It also makes me think I wasted my youth by focusing on security.
I cannot thank you enough for this.
