Interesting family. From memory ( very dodgy) his father developed a 'system' that he put to good effect in Monte Carlo. Noel put together the Railton cars (had one once) and I think his son Lance might have instigated but was certainly involved in the big crash at Le Mans that killed a lot of people and resulted in MB withdrawing from motor racing.
His development of the prefabrication process (Fairmile Marine) for MGBs etc during WWII was groundbreaking.
There is a not very good book about him, lived somewhere between Cobham or Esher? A great story with lots of ups and downs.
