It seems that Neville was involved in many piloting activities. My late father in law worked for Dowty Rotol and was regularly flown to business meetings by him in the company Dove. I was fortunate to meet him when he presented me with a flying badge after I renewed my PPL. I met him several times after that in the bar at the Bournemouth Flying Club after he had flown back from some do or other, along with his wife. The last time I met him he had just returned from a lunch gathering for surviving Test Pilots from his era. Apparently he was the only one still flying.
His AA5 G ZERO was available for hire at Compton Abbas a while ago and I was very tempted but it was a bit expensive for my budget.
