Ok as my previous query hasn't elicited any replies, let me ask the question differently....
Having looked at Ken Delve's book "The military airfields of Britain - East Anglia" it seems that during 1919 the RAF withdrew entirely from Norfolk. Is this correct? Was air defence for the county being provided from elsewhere? I can't believe we had wound down to the extent of having no air defence at all on this part of the East Coast!
