I have jpg copies of every brochure that Ibanez put out on the ATK series, which includes Asia, Europe, and North America. It's late, and I'm bleary-eyed, but I haven't seen a natural finish from the 90's. In the mid 2000's yes.... It looks like whatever original finish it may have had was stripped of (very well) and a clear coat sprayed on. The clear coat just doesn't look OEM to me, as it's not deep-looking, nor polished to a mirror finish. If anyone thinks I'm incorrect, I'll look at my brochure pictures when I'm sober, and in the light of day...
All that aside, that's a bit pricey for a 4-string - it should be more in the $325-400 price range I think, and $70 for shipping, depending on where you are in relation to the seller, seems fair...
