Few years ago I acquired an old soviet film called KN 3 (CINEMA NEGATIVE). It is monochromatic motion picture film from SVEMA - film manufacturer who bringed us it's famous Svema Foto 64 and others.
I paid 50 euros for five cans of 300m/1000ft film. As far as I know (this information came from old lithuanian cinema geeks) the film was rated @ 320 ASA when it was fresh.
A Can of Svema KN 3 looks something like that (H is N in kirylica)
