The ESP Guitar Company

Hi people, new kid* on the board! My primary reason for signing up at the moment is because I'm thinking of buying a second hand LTD SC-607b, which the owner bought sometime in ‘09. But I would like to know if this would be the discontinued mahogany version or the new alder version? The owner says its mahogany but even he’s not sure now, as he doesn’t have an official ESP/LTD certificate given with the guitar to certify the wood selection and I’ve noticed a few stores haven’t updated the details of this model yet, unless they’re old stock? The serial is w09020793 if that helps? Thanks
