Further information - my posted advert was from 1967, which doesn't seem very long ago to me, but it's over 50 years, so I suppose the car could have deteriorated over the years. It had just been refurbished in 1967 so I guess Mr Gilmore didn't buy it till some time later.
On the DVLA site, it's shown as a green Bentley with a 2940cc (!) engine. It was first registered in November 1993 so I assume that it was off the road for some time with the number plate on retention. It has been untaxed since August 2016.
