I have five rolls of Ektachrome 160T, expired in 07/2002 and five rolls of Portra 100T, expired in 10/2001. They are 120 film.
The films came with a camera I bought, so I have no information on storage conditions other than the guy said they were stored well. Other expired films from the same guy are of good quality.
As I am not familiar with tungsten films I rather sell them to someone who knows how to make the best of them.
