Maybe it's all Fuji-Chrome? I can't tell you for sure until I get back home. I am at my cottage and the film is not, but I will check Monday when I get home. I do know it is dated 1987 and it is 50D and 64T. So, now that I think about it you are more than likely right. Would I treat the Fuji-Chrome much different than if it were old, expired Velvia?
