Walrus - Admiral's Barge was more often used for the fixed wing.
The Heron at Yeovilton was FONAC's (Flag Officer Naval Air Command) Barge.
The Wessex Vs were the Green Parrots. They even had a slot by the cabin door for the appropriate metal flag plate denoting the Flag Rank of the passenger to be dropped into.
Woe betide you if you made a mistake with the number of Balls the Admiral merited!
Sad to see the ultimate fate of XT 772 but I guess if you give something to the Crabs to look after....
