henryj that isn't the J-160. The guitar in the exhibition is John's Peace guitar, the one he drew the John & Yoko faces on the front of the body of the guitar. He used it at the Bed-In and played Give Peace a Chance. (I know it gets confusing some times. )
Okay, Rocky, I stand corrected. But it's still a J-160e, just not THE J-160e. I did some browsing and learned that Brian Epstein had purchased an additional pair of J-160es for John and George. According to the source, John painted his a light blue color before sanding the finish off.
