I am trying to identify a vintage Gibson hollow body guitar. I have searched inside the f holes and can find neither a in stamp or a sticker with model, serial, etc. I searched images of vintage Gibsons and this one appears to possibly be an ES-125. Is there any other way to id this guitar besides a sticker or ink stamp? I have enclosed a photo of the headstock and the body of the guitar. Any help would be truly appreciated. Thanks
