Re: Help me identify this pickup?
No ID marks anywhere, it could be anything.
Does the cable that runs from the pickup look the same as the one for the neck? Is it wrapped in a braided wire shield, or grey rubbery shield?
What about the conductors to the switch - same as for the neck pickup?
That might help narrow it down as to whether it's a Gibson or not. Maybe.
Might want to look into original PAFs and see what markings (if any) they had.
It could be an early non-baseplate-logo Duncan that simply lost its sticker, or it could be worth your house.
