Re: Pentax auto 110 and 16mm film
John & nexus757 are correct.
I used film reloads sold by Joe McGloin at Goat Hill Photo before I was brave enough to try sitting my own strips.
When you slit film, get a length of wooden dowel rod or cut a notch in a yardstick's edge to be a film length guide. Measure your old film strip when you crack open a 110 cassette. Probably about 18"?
I also wanted to say the Pentax takes 2 throws of the film advance lever for each frame.
