This guitar has been a real mystery for anyone that knows about Ovation acoustics, as to its exact origins. I know that there are a lot of one-offs out there and this could be a custom, but it could also just be a 'lesser' model.

The little info I have is that it was a prototype or pre-production model used in a promo photo shoot about 7+ years ago when DW owned Ovation. The guitar has no sticker and no serial to be found anywhere on the body. I haven't been able to find any similar photos of other guitars with this bird's eye maple mint burst finish, the binding, custom inlays, truss rod, and epaulets in this style, which are not veiny and are flush with the body. Regarding the lack of sticker, there's no sticker residue in the bowl and no evidence that there ever was one but who knows.

EDIT: The closest thing I could come up with was that this a 6778 LX of some sort however there's no neck binding. 

Can any of you experts ID it? More detailed photos here: https://photos.app.goo.gl/ehyYiyoNcYHVJxxU8
