I cant add much to the topic except to say there is quite a bit of Art in regards to firearms.
Many hears ago I was working on a degree in Police Administration. You had to take a bunch of Soc/Phy classes. No knowing what it was, (I assumed it had to do with Soc/phy, I signed up for a Humanities Class.
Wrong, it was about ART. I know nothing of art, nor was I interested. The grade was based on two main topics, The book "Agony and Ecstasy" about Michel Anaglo, which I never was able to get through, and we had to write a lengthily paper on some sort of Art.
I decided to write a paper on the Art found on firearms. My instructor was a rabid anti gun guy and told me up front would probably effect my grade. I told him that my paper wouldn't be about guns but art.
Turns out there is tons of information about art found on guns, and the meanings of the engravings and art. Take into account there was no internet in those days.
I found it quite interesting and really got involved and ended up with an extensive paper which earned me an "A" from my anti gun instructor.
My paper was good enough to make up for not reading that idiotic book and I ended up with a B in the class.
If one searches, you'll find art on firearms not just pretty, but has a story, a back ground that is pretty interesting.
Wish I'd kept that paper.... but I wasn't into such foolishness back then, I just wanted to survive college.
