More Wessex ..
A 'White Top' Wessex (aka Green Parrot or Admiral's Barge), used for liaison duties by senior Royal Navy types and most probably a Mk V, departs Battersea Heliport in London on 17th August 1973 and overflys a 'parked' Hughes 300 (G-AXXD) belonging to Twyford Moors Helicopters
Given the year, one has to assume there is a possibility that PPRuNer Sandy Toad was at the helm of this 'barge'!
