I think you will have to remove the metal fittings and sand back the lock down bar. The problem might be that some of the scratches might be so deep that it cannot be sanded back completely, and those scratches will be more pronounced. I would attempt to sand it back. As with all the wooden skirtings and siderails, these should be lacquered or varnished to the same finish.
I'll have a look for the cigarette holder this weekend and if there's anything else you need, just let me know (before the weekend).
