I think these are just his notes on his thesis, rather than his actual thesis. I don't know what the source is, but this same document was posted on HN as his `handwritten notes for his Ph.D' (https://news.ycombinator.com/item?id=6002173 https://news.ycombinator.com/item?id=6002173). It's incomplete, full of corrections and deletions and covered in notes that are not referenced in the text. Cambridge keeps a copy of theses submitted since 1920, so they should have a hardcopy of the real thing somewhere, but I wouldn't have thought it had been digitised. How fantastic it would be if they did though!
