I looked at that site and they have a history group - definitely worth a phone call.
The car was sold on in 1968. During it's time in W le W it had the rear half of its body chopped off and replace with a wooden flatbed truck body. It was used as a garage hack!
You never know, they might be able to find me a photo of it in that state - which will probably upset me

And I will research the man a bit too. He does sound interesting - very much a part of the car's history, especially if he kept it from 1928 to 1960 - that's a LONG time to own a car..
