I found a very good copy of the user manual at
http://www.central-manuals.com/instructions_manual_user_guide_camera/graflex.php
After repairing one and loading film according to the instructions there were several frames left after exposing 10. When I opened the camera there were 3 frames left.
I noticed that modern 120 film is marked 6x9 on the bottom of the film where the Ruby window is on the camera, 6x6 in the center of the backing paper aligns with the small window in the center of the back of the camera, and the top is marked for 6x4.5. There is no 6x7 markings on the backing paper for Arista EDU, Kodak, or Ilford films.

Where do you wind the film to in the Ruby window on the lower right side?
Where do you set the film frame indicator, to the immediate left of the S or closer to the 9?
