To save yourself from blindly advancing the film, I suggest with the lid just about closed (this mostly for shorter people), shine the flashlight from the inside out through the film.
If you can see the flashlight through the film, you'll be able to see the glowing metal source. The flashlight is conveniently small enough to make this an easy check.

Subject: Film on order for View Port OK to use
Jim Haydon is still finding too many blank areas on the film for the Polarized window. We are going through the
film too fast. Here is a clue, If you turn the knob clockwise less than a quarter turn and you still can't see,
IT'S NOT THE FILM. It would be another problem / reason that you can see. Check the shutter knob for the polarized window is in the right position, make sure that the shutter in the chamber has the opening in front.
We should have more film by tomorrow, but Jim has found some areas of the old roll of film that will allow us to run for a week (two feet worth).
