I've just been looking at the film archive on the British Film Institute (BFI) site and they have a number of films that you can view for free relating to Steel and Ebbw Vale features in several of them. They can all be viewed for free and include film and commentary on the opening of the RTB Club and Institute at Ebbw Vale House in 1950, the building of the works in 1937, Ebbw Vale RTB football team winning the Lever Cup against the midlands side Cookley and other interesting sections about life in the Works. It's well worth a look even though one section does state "Ebbw Vale England";
