The black plastic around the pole pieces. The shape is different on the bass side of the pickup. On an H the two screws have like a circle around them and there isn't any plastic in between them. And on an HS/HH the humbucker has the black plastic connecting the two screws and is like scooped if that makes sense. Take a close look at the bass side of the humbucker and you should see what I mean.
