Hi Jim,
I defer to your and others opinions on this because I have not had the pleasure of handling a lot of high-end British and European guns. The ones I've examined were well maintained and conserved. For example, on a silver mounted pistol by Barbar, the chiseled and cast silver mountings were still crisp and the hallmarks clear, although they were lightly polished. Silver is soft and would tend to show effects of vigorous cleaning and polishing. One India pattern musket was polished bright but did not appear to have lost any markings. However, I must admit that all of the dueling pistols that I examined (which were mostly early 19th century guns) had barrels that were rebrowned. I tend to give folks the benefit of the doubt and Feltwad is a man on the scene, so to speak. "A little national pride showing"? Yes, absolutely, on both sides of the Atlantic.
