The beauty of the Lightning OR946 primary flight display system in all its splendor: the large roller-blind attitude indicator next to the the lovely designed combined offset TACAN (a navigation aid) and ILS (Instrument Landing System) display for navigation; a pretty advanced stuff back then.
On the radar scope the necessary. Those hoods were really obtrusive but necessary in those primitive scopes. I love them anyway.
