Unless there's really solid provenance, there are so many differences that I'd assume it's not a Gibson at all.
I suppose all of these
could be mods, but I'm suspicious to say the least.
- Wrong inlays, as Grog pointed out
- The body shape looks a bit off to me, though it's hard to be sure
- Truss rod cover is blank, it doesn't say either "RD Standard Bass" or "RD Artist Bass"
- Non-standard finish, what's up with those stripes?
- Pickguard is totally different shape
- Rear control cover is wrong shape (and ugly as hell, looks like a hack job)
- Both pickups replaced - these don't look like either artist or standard pickups. Neck pickup shouldn't have exposed polepieces, and bridge pickup shape is wrong.
- Controls moved (that's not where an RD standard would have the neck volume, and the switch doesn't look like it's where the original output jack would have been)
- Output jack is moved ... somewhere on the side presumably? Not visible in photos
- Tuning keys replaced, there are visible holes
- It's hard to make out, but the serial number on rear of headstock looks fishy - not enough digits
I'm no expert, but this is just stuff that looks odd to me compared to
