First off,
to the family!
Sorry to say it is NOT an RPM. The stuff inside the curves of the S is a damaged punch theat made the die or the die is damaged and has began to break. Notice the only reference for any known 1974 S/S, the thickness of lower and upper curves are missing and no separation line or split serifs showing on yours.
