Great work. The dirtier, greasier, and powder residue just makes them look and feel like originals. Five years ago I had a white powder horn made for me by Scott Morrison. I was crushed after a couple of years of service it had stains, marks and even a few dings. Last fall Scott was shooting with me and I had that horn with me. He carefully looked it all over from end to end and said "it's about time you got some proper patina on it. Another couple of years and it will be broke in."
