[exray]

Smart money says that if you aren't familiar with old radios then it would probably be a bad idea to do anything to it in hopes of increasing its value. I've seen too many examples of things that have been redone by professional 'furniture' restorers that ruined the item from a 'radio' collector perspective. (Coloring, finish type, etc). A radio is not an old chair

That said, if you were to find a real radio restorer the cost would rarely be recouped upon resale.

If you're intent on selling it I'd recommend doing so as-is. Original examples often are more desirable than a refurbed example - particularly so if the refurb is short on authentic details.

Guessing dollar values is out of the question without seeing photos. (Is my girlfriend pretty?)
