Let's look at this from the cup-half-full point of view.  If this finish is applied over a pristine original finish, it may serve to protect the original finish.  If you can find a way to strip the green without affecting the finish underneath, you may have a hidden gem here.    But if the original finish was stripped to put this putrescent colour on, you may have to strip it down and recreate the original finish or at least something equivalent like a French polish shellac finish.  Ugly, yes, but this is reversible.
