Submarine Question - Barb or Tang film footage!

[SnowCajun]

I have a question, is there any footage of either the USS Barb or the USS Tang floating around? Fluckey's book, Thunder Below, speaks of a film guy being on the USS Barb on her last patrol, he also speaks of the films made by the President with his personal movie camera, and also of still shots through the periscope, has all of this vanished? Does anyone have a clue?

Thanks,
