Do you think the finish is too clean? The guitar seems to be very clean, a bit weird to me too. The sideways vibrola was switched to trapeze.
It's hard to be certain from the photos you've got, but it definitely seems possible, if not probable. It's all very shiny and looks devoid of any checking/wear, plus the binding looks really white. Not fully impossible if it's been totally under the bed, but man, for pushing 60 years old, most will yellow and check a little, even if left more-or-less unplayed. I also notice that the pickup cavities look super clean and shiny, free of old polishing compound and the sort of dust, grime, lint and skin flakes that usually accumulate in there. ...and that writing on the pickup suggests it's been out so, if it's original, then that supports the guitar being a refin and, if it's
not a refin, then it supports the pickup having been replaced, whether or not it's an actual PAF.
