Hi there, if you what you want is an alembic, you will be missing out greatly if you have a non alembic tone circuit in that bass, apart from the build quality, playability etc, the thing that separates Alembic basses from the rest is the tonal capabilities of the filter based electronics. Without that the bass will not sound like an alembic bass. That being the case if the bass was going cheap, you may be able to send it back to Alembic and have proper series electronics installed and a refurb. (not cheap)
My first observation is that the pickups look far too new to be original based on the age of the bass and if as you say the electronics are not alembic, then the pickups are also unlikely to be series I single coil pickups as if they were you would almost certainly need the additional hum-cancelling circuit to keep the bass noise free. So I would suggest those are alembic regular hum-cancelling pickups that are usually found in the non-series bass range alembics.
If I were considering purchasing, I would ask the seller for more photo's of the bass including closeups of the neck/headstock repair, the back of the bass and inside the electronics cavity and battery cover. Then post them on here so that we can see what in fact is in there. The serial number should be stamped on the top of the headstock and/or on the bottom of the fretboard although from the picture it looks like that may have been filed off unless it's a trick of the light. So there may be a question to ask there.
If you get us more info on the bass and photo's, there is a lot more we can help you out with. There are some truly knowledgeable guys here who are as passionate about others getting the right alembic as they are about buying their own.
Also be aware that there are some alembic copies, (Fernandes), around and if you want an alembic, then you don't want to find you have bought one of those copies. I'm not implying that I think this one is a fake, just making you aware there are some around.
