You have an interesting rifle, but we need to see a few more details of the gun before making an assessment. Perhaps "standard" type photos would be of greatest help. Those include: 1) a "half shot" of the front, showing from the butt plate out to about 8" past the lock plate; 2) half shot of rear, showing from butt plate out to about 8" past where lock sits on other side, 3) a full length view of the front side of the gun, 4) picture of what remains of the barrel signature; 5) picture of the tang at the back of the barrel, 6) picture of rear ramrod pipe with several inches of stock wood on either side, 6) picture of muzzle showing last 6" of forestock so we can see how ramrod channel terminates.
All photos should be taken perpendicular to, or directly over, the gun, so no angle distorts the view or dimensions. It may have southern roots based on the simplicity of stocking with triangular butt with grease hole, but the guard's width and style don't appear southen at first glance, so we need to see additional details to better understand what you really have.
