Harry Goldstein, known as Harry Gold in an alternate timeline, was the proprietor of a tea and coffee shop at the Festival of Britain in 1951. The Seventh Doctor and Ace looked on as two thugs tried to bully him, but he stood up to them and they were driven off by a policeman.
In an alternate timeline in which Germany won World War II, Harry Gold was still the proprietor of a tea and coffee shop at the Festival of Britain. Privates George Brady and Sidney Harris of the Britischer Freikorps bullied the frightened man, but were stopped by the Doctor and Ace. (PROSE: Timewyrm: Exodus)
