Well, I had very little luck tracking down info on the film also, but did come up with this interesting find. In my search I found several references to a heart surgery/examine a talking about what showed up on certain frames of "Ilford Cinegram" film in relationship to the heart going through it's beating cycle. I assume they were using some kind of movie imaging to study the heart valves in action and Cinegram was the film used. I then thought it had to be xray film, but didn't know. JohnW
