I have a fair bit of the sort of footage you are talking about (if i can find it)
Its in one or other of my many boxes stashed around the country.
It is VHS so i will have to try some E-Jiggerypokery to get it into a useable format.
Unfortunately a lot of stuff had to be destroyed a few years ago because of the rule changes (and i wasnt going to risk a stretch for the sake of a video or two) but what i still have might be of interest.
No, there was a stratum of the Corps which was allowed to use the Spotmatics, but not the heavier lenses. They had a very strict ration of fix too, as they tended to sip it if left alone in their darkrooms.
