Thanks for the tip Bob, I'll pass it along.
My friend is a very experienced antique arms collector, but just "saw the light" in the last year or so, and is getting into long rifles. Actually, he bought his first antique firearm when I was only 10 years old. That was 1958. He's funny, in the last three weeks he bought a bunch of books on long rifles, including the new Moravian book, Kindig's book, etc, etc. By the way he is Scots-Irish (stubborn) like half of me, so I know he'll be around a few more years.
