Treadigraph: You are always welcome in helicopter nostalgia territory and you've struck luck with GAZY-B in that she still 'lives' (albeit in static form) at the helicopter museum at Weston-super-de-la-Mare!
The story of her restoration can be found here:
Restoring the Bell 47H-1
At the museum she wears a predominantly red scheme based on the colours she wore when she was sent to Antarctica between 1957-59 where she flew from the support ship the MV Polarhav and the King Baudoin Station in support of the Belgian Antarctic Expedition.
After her polar expedition she remained in the cooler climes being sold to Norway then Sweden prior to arriving in the UK in June 1972 where she became the possession of Tywford Moors Helicopters until she was bought by your friend George Watt of Olivers Farm in Lindford, Hampshire in February 1973.
This is probably how you remember her though:
Bell 47H-1 G-AZYB at RAF Greenham Common on 7th July 1974. The craft was destroyed ten years later on 21st April 1984 at St. Mary Bourne near Thruxton.
