Ok, the pictures help a lot but there are still some questions.
First, this is clearly a Japanese-made model. The serial number and headstock shape indicate it was made in 2002. The pickups and the plastic pickup surrounds have been changed.
With Japanese electronics, a medium neck tenon and no fret end binding it can't be an LS320. With a 2-piece back it is most likely an LS75F but if the maple top is solid and the fretboard is ebony it could be an LS200. I've never seen an LS75f which didn't have a pickguard hole, but I know the LS200's came without those holes drilled.
The pictures are not good enough to know whether the fretboard is ebony or the top is solid. Look in the pickup cavities again. Does the middle join line up inside the cavity? Do the grain lines line up on the top and sides?
