I'm with you on this, Guy, although I assume the PA attribution has some basis. Transplant to NC via several moves in Valley of Va.. would be my guess. The sideplate (not unlike Upper Valley designs), patchbox and star would not be impossible anywhere, although the patchbox looks more at home in NC outside of PA. Something about the toe line is remarkable. The double molding line and the stepped wrist are early (as suggested by BP) Va. or NC, but don't look like SW Va. typically does due to lines cut in BP, esp. in conjunction with that curve. The tang looks dubious to me, but suggests SW Va. or more likely NC in light of the other things.
