Actually I believe you are mistaken regarding the Fraternity, I know a Fraternity Priest and they are not "forbidden" to use the 1976 as it is (unfortunate as that may be) the normative for the Church.
I think you would be very hard pressed to find one who uses the 1976 (if there is even one) but it is probable.
You clearly know more than I do. In my area, however, they do not say Novus Ordo, at least not in public.
