 I think that you may have to strip the top and the control panel, the lacquer on top looks like it's dead and flaking off due to water damage, plus it looks like there is a burn mark, trying to touch up things like that never looks quite right, you may want to strip the shoulder sections on top as well, for similar reasons. It's a common problem with any old console that was left to the clutches of silly housewives who insisted on putting potted plants on top of radio cabinets, or from drinkers and smokers using the radio cabinet as a bar top and or ashtray. Now if you are careful you can strip around the decals to save them, though they are readily available from Radio Daze. To get those panels to match the rest you will have to use a light walnut tone spray, the dye based type, for the base of the cabinet it was either medium walnut or perfect brown, again dye based.
