EDIT: Sorry, I misunderstood your question. It's probably an IP in bad shape that is the reason for some of it if I would make a guess.
What does IP stand for in this context?
Inter positive print (I think). Someone else might explain this clearer than me but the way I sort it out in my head is that you've got the original negative and then a copy of that and then a copy of the copy etc. The thing is the original negative is not supposed to make loads of copies from so it keeps it in great condition except one rumour is that they made 100 technicolor prints of the original negative, combined with poor storage is why the original negative itself is damaged through colour loss.
