For years I have been interested to know if there really was a wartime wind-up radio as I saw one on an old film but didn't remember what film it was from.
The film was "The sea shall not have them" which was recently broadcast on Freeview. The radio appears in scenes in a liferaft.
Fortunately the relevant scene appears in this video:

Was this a real radio?
