Humps mean the neck is set wrong. Cronic problem on old martins and other guitars as well. First thing I check when buying a used martin. One dealer I
know of sends em back immediately when they come in like that. It is not
a fretboard issue the fretboard just follows the neck it is a neck issue. They
will need to reset the neck to get the hump our permanently. Lots of folk
just do a fret job and plane the fretboard insteed but to me a hump means
the neck is pitched wrong and needs a set .
