I have two similar sets, but they are the 1946 versions, and the hardware was copper painted near as I can tell, not plated. Even if they were plated I would not go to the trouble or expense of having that redone, these sets are very common, Philco literally built 100s of thousands of them so it would not be hard to find a better example. The wooden parts are maple or some other blond hardwood, not walnut, it could also have been beech or birch.
