Have you tried to see if the frozen part is in tuning cap or the gear that drives it? From the pictures (and they do not have fine details) I cannot see the space for a really complex pot metal box there, so hopefully the ole liquid wrench will do the trick, but of course Arran is right and you do want to do first things first and make sure you are not spending time and money on something that will not be easily restoreable.
