Cory,
This was a refinish. Not too complicated.
Ferric nitrate stain, 3 or 4 coats of Chambers oil, patina added with spar varnish tinted with black and burnt sienna oil paint, then a couple more coats of spar varnish. When dry, rubbed back and evened out with one more coat of Chambers oil.
Sounds complicated, but the spar dries quickly, (about an hour), so done in a couple of days.
