Thanks for your interest Helig, unfortunately the picture in the book is of a car similar to the one that Hugo has posted above, a 1936 Ford Standard.
Our car is a 1926 Bullnose Morris MG Super Sports, now in two tone blue, but in Scribbans ownership it was originally engine turned aluminium on the bottom and maroon on top, although the log book shows that he had it re-sprayed to green and putty in 1928. Perhaps a sop to a more sombre era of the coming depression?
I have posted a picture on this forum under the 'Hobbies and interests' - 'Cars' on Page 50, Reply No 745.
Try getting DVLA to register 'putty' as a colour on a V5!
I had seen the Birmingham History web page, but did not post on it as it was the same day I joined here, and didn't want too much going on at once. There is also
another good thread about the Local Defence Volunteers that were based at his residence at Little Aston Hall nr Sutton Coldfield.
As it says in the history of Villa Marina Harry died in 1936 before it was completed, sadly also the year he was banned from driving for life following an accident in one of his Rolls Royces.
