The Luscombe 8A (I don't believe the 8 ) had a letter of limited
aerobatic capability from the CAA dated 1947 included in the aircraft's
operating manual. This letter listed specific aerobatic maneuvers
approved for the 8A after joint tests between Luscombe and the CAA were
performed.

Do you recall if snap rolls were among those maneuvers listed in that
letter?
