I have recently come into a stock of this film. The information I have suggests it is(was) a high-speed recording film. The supply I have is dated from the late 1980's and supposedly stored in a basement. Today I loaded a short roll, set the meter for 1600iso and took pictures around the yard. Developed in Diafine (4+4), the negatives are very thin, several almost nonexistent. I realise that I overestimated the speed and ask if anyone has an idea of what I should expect from this stuff.
TIA
