I was gifted this Lawson electric clock that needed a bit of TLC, so I sanded it down and tired to refinish it, but the wood turned darker. I assumed it had a Shellac finish and thats what gave it its warm amber glow, but when I tired clear and amber shellac, the wood got even darker. I also tried a clear poly coat just to see what how it'd look. Any ideas how to restore it back to its amber finish?
