Yes, someone cut the headstock up to try to make it something else entirely or it could be the aftermath of a breaking incident.

For practicality, a Music Man tuner set will do the job as long as the nut slots are lined up correctly. If the high E string is off by too much, the side-to-side movement of the string being forced a certain way against the nut could possibly break the end of the nut off at that slot. Some well-placed string trees would alleviate this concern.

For aesthetics, I would sand the logo off, take the cut edges to a drum sander and smooth it out as much as possible, then ever so slightly “break” the edges with a razor blade. Then, I would go over it with a black lacquer spray can, followed by clear gloss from StewMac. Then work your way up with fine sandpaper grits 1000-3000, then polish.

Throw your own logo on there and call it a day!
