As I told you elsewhere, in the 19th century everyone did the photographic stuff him- (or her-!) self. And then came Kodak. But not in the CCCP. The amateurs (Lubitel!) refilled the cassettes that came with the 135camera, and developed at home, in the closet, under a blanket, in the standard drum.
But: in the nineties you could buy film in cassette, very modern. (And 20 kopeke more.)
I opened a box yesterday and what a surprise: no fancy metal throw-away, but a reloadable plastic cassette!
How very sensible, and "environmental".
