Superb work, Hugh. Amazing what you did. You saved a good gun from future neglect and as a potential 'parts gun'. As it happens, I have the 'almost' twin of this piece, with the exception that mine is in untouched original condition. The finish on mine is a little blonder than this one and mine has no toe plate; the patchbox side plates are overshot as well. They do not terminate at the lid hinge. Same box though and probably identical carving. Likely, the same maker.
The best compliment that I can give you is that in the 'after' photos, my eye cannot detect the work you did on this old girl to bring her back. A fine artistic effort!!!
