I've always liked Bob Symes.

A genuinely cheerful nice but completely fictional stereotype. Received pronounciation, bushy facial hair, tweed or houndstooth jacket, tie, and collar, even the plus-fours. the stereotype British hizzlor'ship.

Reality is he was of landed upbringing, of the manor borne but in Austria, and his family were Jewish refugees before the war. Interesting life story behind that walking stereotype...
