Many thanks Jan and Dominik and giannakis. I bought this film mid-2016, in Bucharest. The box is grey, the lettering is b&w/red and the 'new emulsion', and '400 ISO' is printed in green. As far as I remember, it was not very expensive. It expires Nov 2019. I'll give it my best and post whenever I can develop & scan the film in Ho Chi Minh City. Many thanks for your feedback.
On a related note, I have some TriX and Tmax...expired about a year and a half ago. These rolls were in the freezer for about a year. I am currently living in the tropics and I wonder if these rolls will have degraded a lot or a little. Many thanks for your best advice. Cheers, Peter
