I am not sure if this provides a definitive answer to the fan question. There was discussion here some years ago about this subject. I, like you have over the years seen numerous freshly discovered cars with completely unpainted fans, however I have also come across fans with what appears to be remnant's of original red paint. It is of course very difficult the be certain if said red paint was applied by the factory or an early owner. As I recall others here had views supporting red paint and some could present evidence to back up their views. I am perhaps not 100% convinced but I feel there is enough weight of evidence to suggest the at least some sevens left the works with red fans.
