Westland Whirlwind HAR.10

This photo of a Westland Whirlwind HAR.10 helicopter, shot in the mid 1970s, was almost certainly taken at an aviation museum or collection rather than at an active airfield. Behind the helicopter we can see a Vickers Viscount in Cambrian Airways colours which certainly suggests that this was at a UK museum, and one that displays post-war civil and military types together.
