Remember, you'll need actual W&B data for the actual aircraft for it to
be a legal flying copy.

Actually, it needs to be the actual maintained copy of the manual for
it to be legal for a 152. Your "extra" copy with a copy of the actual
aircraft w&b is useful for planning purposes (oddly, through all the
flight operations I've been in, only one gave us the W&B info for the
fleet so we had it prior to coming to the airport). It will not
suffice if the "proper" book is missing from the plane.
