Even if the shaded parts were stripped before being primed, and then painted, the wood in those areas is tight grained, something like poplar, not open grained, so it shouldn't be too hard to remove, except in the moldings. The real P.I.T.A grain to get paint out of is Oak, Ash, or Mahogany, those are very open grained woods, walnut less so, but then again the lacquer was less likely to flake off of those areas as well, stiff brush or nylon scouring pad to remove the paint residue, in repeated sessions.
