Maybe my eyes are deceiving me, but I also saw the (very capable) bassist of the Beth Hart Band, Herr Tom Lily, on a Rockpalast feature on German TV from a Bonn gig in March 2011 at the local Crossroads (no Clapton affiliation) festival there and he played that thing on at least two tracks. It is apparently long scale, cherry fin, has a Gibson logo headstock with the crown inlay, features two pups, with the bridge one though farther to the middle than you would know from a vintage short scale EB-2. Pot positioning untypical too. And it looked brandnew.
Gibson Custom Shop one off? Luthier project? Modified Epi Rivoli (the Japanese version)? Your guess is as good as mine. I've written Herr Lily an email on the band's website, maybe he will spoil us with a reply.
Compelling scientific evidence, how could we ever do without it here?, at 1.33:
Very good views of it here, looks definitely long scale to me, or is this just a case of neck envy from my side?
