Out and about in Surrey on Sunday I happened upon a scene that could have been played out 77 years ago. It was mid-afternoon on that glorious sunshiny day. Lunch just about over. The pub had a large garden with tables neatly shaded by leafy pergolas. A family group had finished their meal but were still huddled round the table, on which in pride of place, amid the empty plates and half-filled glasses, sat a green-and-cream Roberts, aerial aloft.
