I have also obtained film from John Schwind (years ago) and it worked perfectly in my old 8mm cameras.
Oh boy, that's great. I'm going to buy me some of this stuff. I remember watching vacation movies from early 1960's of myself and my sister, when I was 3 and she was 8, playing with our dogs in 1960 or so. Terrible quality, but still cool as hell. It's all in my basement, along with the projector.
All paths are the same: they lead nowhere. Choose the one that has heart.
