Hello,
I have got my fingers on this J-200. I think this is a copy but maybe someone has any idea when and where it was made. It looks vintage because the white parts have nicely yellowed. There is no serial number on the headstock. It looks like there has been a rectangular label which is now replaced with Gibson's original orange label but the writings are all done by pencil. Ink stamped serial is also seen on neck and body joint area when looking through soundhole. According to my knowledge the Japanese copymakers had their own names on headstock. Perhaps someone has any idea.
