It's the EB-3L (34.5" scale). You can tell by looking at it. I have a '72, which has the 2-point bridge (that one has the 3-point) but it's still in the same place. Great bass, someone should really jump on this. They are actually very versatile basses au contraire to popular belief , especially the ones with the mid pickup placement (like that one).
Good luck. I'd be making you an offer if I already didn't have two of those...
