As you can see in the email above from Deb, she has the manuscripts in Hanover. She said in Sep 2023 that she got 600 or so pages digitized, but I have yet to see any of those digitized copies. I obviously 100% believe her because she has literally no reason to lie about this, but she lives a busy life and doesn't have the time to serve as an archivist for her dead brother. As I live in a different state than Deb, I am not able to just fly to her house and help her and she is not willing to ship the manuscripts for obvious reasons (sentimental and material ones).
As for the actual film, she has told me in the past she believes she has a copy, but digitizing it would be prohibitively expensive.
I am a uni student as well as working in the arts industry, which is why I haven't been as active on here as I should be.
My apologies,
Charlie
