This should be a KCM-00 standard concert made of Koa. A look up the soundhole should show a year stamp—and if memory serves, a factory special is a blemished model (usually minor and certainly won’t impact playability or sound).
Had I not discovered a mislabeled 2004 KoAloha concert a few months ago (I bought it and ran), I would have jumped on this item. Factory special factored in, you’re not going to find a Koa instrument of this quality, with a case, shipped for this price very often.
