If someone has slobbed shellac over the original lacquer finish then alcohol should remove it, either ethyl or isopropyl alcohol, without damaging the original finish. If the dial is similar to a 116 series set then there should be a locking ring that holds the dial on it's hub, sort of a flat disk with two tabs sticking out, give it a 1/4 turn and it and the dial should come off.
