"Nothing bothers me more than to see a contemporary gunmaker copy an obvious mistake from an original and then when critiqued or questioned about it they respond by saying, "That's how it was on the original". Come on, strive to be a better student than that."
That's pretty much where I was going, but Dave said it much better. Again, I tend to look at this as a form of revival art, or an evolution of the originals that we all admire so much. I'll probably get in trouble here, but so many times you'll see carving or engraving that have flat spots on volutes, or some other "mistake", and we kind of shrug and say "well, that's the way originals look." Many do, but to me a flat spot is a flat spot, and whether it was executed 250 years ago, or 250 hours ago, it doesn't look "right". I've certainly done my fair share of flat spots, but continually strive not to. I also hear people say "it looks too perfect", or "it's too good" (what ever "it" is), "doesn't capture the feel of an original", etc., and think that's crazy. Like saying there's too much money in the bank account, or something. I think that's where the revival and evolution comes in. Learn from the old Masters, study their work, but don't be afraid to follow your own instincts and strive for excellence.
I don't think Mark's take on "fixing" some things is arrogance either. Again, you're learning from the old Masters, and trying to improve as a student of their work.
