I'm trying to figure out what year this SG is. The guy selling it said the serial number was sanded off. But he says he knows it's a '69 because the second owner (he is the third) he used to have the paper work. I noticed two fishy things in these photos: the dot in the i appears to be there (attachment: gibson8) but is not in the other (attachment: gibson1). Same for the truss rod cover it's blank in one but the other says SG. Upon looking at the photos to upload them I noticed a small watermark in the corner does anyone recognize it? The last three are photos he sent me when I asked for more pictures. He did say he replaced the tuning machines with Grover Deluxe Tuning machines. Any opinions would be greatly apreciated UPDATE: I found the original posting with those first four pictures on worthapedia maybe he's the guy who bought it but I confronted him about this. Will update again with what he replied.
