It seems to me the info I've seen from collectors does place them in a 'desirable' catagory. I don't know if there was a specific marking for them so the collectors today recognize them or, they had a really good smith who liked to 'hone' his craft. The textile mill may have turned out less than high quality osnaburg but I don't know of a textile mill making swords. Like we don't have enough to think on, here is one more little tidbit to explore. Dang puzzle keeps growing.
