Box 125, I do not think your still is from "Abus de Confience" at all. I do not think it comes from any movie drama. I am sure it has come up on this site before (though I can't find it now). It is from an old newsreel clip about an exhibition (either Swedish or Danish, I think - it was attended by the King and Queen of the country concerned) and this was a Rubbertex section. The models held up numbers to identify the rainwear. That's why the girl holds up the number 10. So the answer to your question is she is not an actress but an anonymous model.
frogmac, the film "Boys in Brown" is available in its entirety on You-Tube now. The photo is taken from the sequence that occurs after about 36mins.
There are many more films with this kind of mac from the 1940's and 1950's mainly. I'm not sure what you have already seen, but as I said to Box 125 earlier in this thread, the Lakeland Elements site (Rainwear in Films) has a comprehensive listing of all films containing rainwear (of all types) that have been discovered. I am one of the contributors to that site.
