Please find the post on 4/13/17 by Dothedew on the 3rd page of The Other Gibsons page of his 2015 Non Varitone VOS 345. He has very good photos of his guitar and mine is only a few serial numbers away from his. By coincidence, they are almost identical and eerily similar in the grain and flame....mine is a touch more subdued, but overall has more flame covering the front of the guitar. I did replace the control knobs offered by Philadelphia Luthier's Supply, which are much more accurate to vintage spec than the factory Gibson knobs. Mine does have the "window" cut in the center block, even though there is no Varitone installed....doesn't seem to hurt tone or sustain one bit.
