Clips from the Royal visit to Ulster

The above images are from a "British Pathe" news reel named "Royal Visit to Ulster", dated 26/07/1945, when Madiz (then named Hiniesta) was assigned as "Royal Patrol Yacht" (Click here for related video). She carried King George VI, Queen Elizabeth and Princess Elisabeth (the current Queen) on a Victory Tour (More...)

What she must have looked like then...
