HEURTIER STEREOVOX SUPER 8MM STEREO SOUND PROJECTOR - REWINDING A FILM

This guide is on how to rewind a film after it has run all the way through the Heurtier Stereovox Super 8mm Stereo Sound Projector as I don't believe the manual is particularly clear on how to carry this out. Apologies for the 'wobble-cam' as I was trying to hold the phone while demonstrating how to use this projector.
