My thoughts exactly. Did find this though:
Those look like Gotoh tuners.
There's one in the Oddball Fenders thread on Talkbass as well. So it looks legit
Probably Japan, late 80's, early 90's or something (EDIT: Texsunburst59 is right about the serial on this bass). Can't find any more info on them unfortunately. Fender doesn't even mention them in the "Other Fender Basses 1980s and 1990s" page on their website.
