To Tony Parsons = Thank you for your response - but I cannot load the film. I need to find a manual that explains.

The impossible we do immediately - miracles take a little longer ! I did put a comment after your previous query suggesting you search Google for a source of the manual - have you tried that ? It is also possible that someone may have one for sale on Ebay. If neither of these bring success, contacting Bell and Howell themselves explaining the situation is another avenue to explore. If you have a camera store locally (not a retailer who sells modern cameras as a sideline), you could see if there is someone there who could help you, or they may know someone who can. If there is a camera club where you are, their members may be able to help.
Have you tried YouTube for instructional videos on loading cine projectors ? Even if they do not show your exact model, you may glean sufficient information to enable you to work out how to load film into yours,
Good luck again.
Tony
