Dave,
Your points are well taken and the arguments about what constitutes art are unlikely to ever be settled because of the human penchant to like and to be stirred emotionally by different things. Craftsman, artisan, artist? Yep, I know many people were involved, but great directors make for great symphonic orchestras, yes? All of this work is a composite work of many, many artisans but so is the best British gunmaking of several centuries.
Mike-Your nausea might be an indication of a medical condition and you might want to see a doctor. I hope you looked at the plethora of flintlocks in the second link in my original post where there are a lot of muskets, maybe more to your liking. Out of the 212 guns that come up with a 'flintlock' search there is something for almost anyone to like.
Bama-like you much of it is not to my taste but the skills embodied in the works is astounding (which is why I shared this) and all of this before CNC, electricity and other things we depend on today in our gunmaking.
And finally, I have heard folks describe Jaegers as garish, gaudy, ugly too. Not me. That is right in my element as are the other extraordinary European firearms produced alongside the best of the British. I have a Czech 16 gauge double from the mid-1800's that has extraordinary horn and wood carving and very fine metal engraving and I can tell you it is delightful to hunt birds with something of such beauty.
