Hi,
Kent, I think you misinterpreted that paper. Antique furniture was his business but American long rifles were his hobby and avocation. I think we owe Joe Kindig a lot of deference here with respect to defining what most of us call the "golden age" of Pennsylvania-Kentucky rifles. He based his notion on the study of more rifles than most of us will see in 10 lifetimes and then he did us the great service of writing his book. The beginning of what most of us refer to as the golden age is fairly easy to define, the last couple of years of the American Revolution (1782-1783) when nothing much militarily was going on and the US was starting and recovering from the war. There were a lot of gunsmiths in PA, MD, and northern VA, and probably a lot of competition for customers. That shake up produced a lot of innovative and creative gun work by makers who still carried on strong European traditions of decoration and workmanship, albeit becoming more "Americanized" all the time. The ambiguous part is defining the end point or points because those features and traditions died out over different time periods in different places. Kindig was clear, his golden age started just after the war and lasted 25 to 30 years to about 1815. After that time, the quality and decoration started to decline. It also must be understood that he was referring to long rifles as works of American art not as important utilitarian tools. He doesn't even consider most southern mountain rifles because they came later and were mostly utilitarian. As I wrote previously, the end points are the hard bit because some places carried on artistic quality and creativity long after 1815 but they all mostly petered out by the 1840s. Again, Kindig emphasized the "golden age" rifles as expressions of American decorative arts not as an important technical or utilitarian tool.
