A couple of details that catch my eye include:
1) the iron guard is attached with wood screws rather than pins and bow has a "cup" shape, suggesting a southern origin,
2) the wrist area has an uncommon, soft curve to it, more pronounced than normally seen on guns with triangular butts with straight comb and toe lines, and may help identify the stocker,
3) barrel has been shortened significantly based on rear sight moved far back and shorter distance between two front pipes...probably 5" lost, and longer barrels often indicate a southern rifle.
4) I'd want to take a close look at the triggers when you get the gun in hand, because I'm not sure the front trigger is old/original, and its scroll tab on rear edge is one I haven't seen on a southern gun,
5) I may be wrong on this one, but the missing sliver along the rear forestock appears to have a slightly uneven, "bumpy" edge, suggesting the wood is curly maple rather than walnut.
