David was my gentlemanly, eccentric, kind, next-door neighbour in Gweek in 1978 when I was a newly-married young 2Lt RM and took me under his wing. and I came across him again many times during my time in the Royal Marines and later in Bristow. He was quirky, knowledgeable and I'm very sorry to hear that the big C has taken another gentleman from us.
Requiescat in Pace old comrade.
