Years ago I took a set of PU's out of a 1983 LP Heritage Elite which I still have. They only have the 2737842 numbers on them, but no black pat sticker. But I would bet that they are Swaws? How can I be certain? I would assume that I need to take them apart but what would tell me they are? Also while looking through my parts I found a set of mini humbuckers with the Gibson logo on them. If I remember right, I think they were old. Does anyone know what they are worth?
