Except for the fact that it has features first introduced in 1957 (contoured body, pickguard-mounted controls, and split pickups); another feature, the rosewood fingerboard, introduced in 1959; and a final one, the "tortoise-shell" pickguard, introduced in 1960 and phased out in the late '60's in favor of a black or white unit. Until 1966, the tuners turned "backwards:" that is, you turned the key toward you to tune a string sharper*. That year Forrest White developed a conventional tuner that turned away from you to sharp, just like guitar tuners. Prior to 1964, the tuners didn't sit flush on the headstock, owing to a protruding screw head. That year Fender started drilling out 2 "divots" in the surface of the headstock underneath the tuner plate to allow the tuners to sit flush. Also, in 1966, the pin securing the tuner key was eliminated.
I hope this helps you date the bass. It's a beauty. I'd love to have it!

*If this isn't clear, turn the bass over and look at the threads on the worm gear: if the tops appear to lean to the left, it's a pre-66; if they lean to the right, a '66 or
later.
