I had to go back to the original listing to have a peek. Wow. I have never seen anything like that delamination before. I also checked my Series II graphite necked bass. No delamination at all. Can't even feel the seam. I have no clue.
Maybe Mica can shed some light. Those headstocks are not like the wood ones. The headstocks on the graphite necked basses are hollow. At least mine is.

Just a thought here, Michael. Has your bass ever been heavily "thermo-cycled" ? For example, has it seen time in an airplane cargo hold, first on the hot tarmac followed by a few hours at 35K feet, then back to ambient ground temperature ? The actual term is
thermal expansion coefficient, but the bass would have to be subjected to some swings in temperature in order for it to rear it's ugly head.
Now we really do need for Mica to weigh in. I know the mothership sort of phased out the graphite necks in the early 80's.
