i would agree with Mario in that the southern rifle as many of us think of it today , is a rather later style of rifle . this however doesn’t mean that there were not southern rifles . factually there were . but they just had not came into their own distinct style that most readily recognize today .
if you look at the rifle that Kemper produced its not hard to pick out the Lancaster styling’s . but its also not hard to see that things were changing . IE deeper comb nose relief , slimming and less rounded mortises but and trigger guard changes .
Also one should be aware that just because a person was born in a given area , it doesn’t really mean that a gun they carried would have been from that area . Especially if the family had migrated from somewhere else . There are still family ties and pass downs to consider . It takes often times a couple generations for there to be a drastic change in even the simplest of family heritage . Which also includes the tools and how those tools were used . Before there is a real noticeable change .
that’s what Kemper was actually emulating with his rifle in that there was a change happening , it just wasn’t as instantaneous as a lot of folks think .
I also think one should not fall for the idea that POOR means Poor . It didn’t then and it doesn’t now .
If anything there IMO was an even greater since of family respect then there most certainly is today .
So while an item like a rifle , might have been more simply , that doesn’t mean it was plain and without decoration
But anyway . My advise to you is this . Spend a little more time looking at documented rifles from people who lived in that area search out the rifles or depictions of the known rifles from the battle. Then use and common average of what you find . Your looking at having an investment in your rifle do your best to gather as much info as you can .
My bet however is that when all is said and done your going to end up being real close to a Lancaster that’s slimmed way down and has the transitional appearance like Kempers . If not a rifle that’s along the lines of something even older
