It seems to me the headstock?s VERY big for it to be a broken headstock tip issue, something tells me it was meant to be like that, or either a later mod from a big headstock.
Was it me, I?d send it to the Mothership, have the two neck holes filled in, and reshape the headstock to as close to crown shape as possible. Oh, and a decent hard case for it, too; it deserves it!.
