Thanks again all. I was just enjoying looking at mine on their racks, and thinking about iron being used more in the South than cast brass, thinking of all the American migration patterns and where they'd learned. Trying to determine regional and chorographical trends, like where and why did the ring at the end of the TN hand rail come from? Identifying an individual gunsmith by trigger guard it too difficult, they changed them sometimes with every rifle. But it's great to look at them all at once and think about it.
