Slightly disappointed

Enjoyed the movie, even cried a bit. Slightly disappointed though with the special features. Because we had seen a bit of footage at the end of the movie showing the original striking machinists of Dagenham, I assumed there might be a mini-documentary of the original woman as part of special features. But, no, not a bloody thing. Obviously there is footage someplace of these woman and surely some of it could have been included in special features.

Even Wiki doesn't mention any of the striking women by name. Who were these women?
