I think the pics are uploaded now, thanks Rick, and welcome. Originals would have two holes on the back of each scale. These holes should be tapped with the same thread as the grip screws. Also, copies are usually made by casting molds from an existing pair of originals. This process, unless a pristine pair is copied, takes along all of the wear and tear and/or distortions of the example used. Your grips have one large hole each, and although I can't tell from the pic for sure, the fronts are also suspect.
