Here's a simple example of how changing the colours of wires is irrelevant. Suppose I have a cable with the following voltages at its ends:
+ 12 v. d..c. = Red
- 12 v. d.c. = Blue
0 v. d.c. = Black.
If I extend those wires such that the Red becomes Orange; the Blue becomes Violet and the Black becomes Green, then I will get:
+ 12 v. d.c. = Orange
- 12 v. d.c. = Violet
0 v. d.c. = Green.
and the colours of the 'original' wires are thus irrelevant.
To me that is obvious: I hope it is to you. I do not wish to insult your intelligence: if indeed it appears that I have, that was not intentional and I apologise accordingly. Perhaps I have mis-understood what you have written immediately above, but I have read it through several times. But I am seriously trying to help.

I fully understand that your wiring diagram was based entirely on the readings I supplied, as opposed to the colouring of the wires, that's why I stated ‘’ As I'm sure you have appreciated,’’
The contents that are causing me a modicum of confusion are 1/ that you appear to be of the opinion that this is a modern fan 2/ That it probably doesn't fall into the category of being earthed when the structure is of cast iron and aluminium 3/ Your diagram appears to only cater for four wires emanating from the motor windings when there are five. I use the word appear in the context that perhaps in my limited ability of reading electrical diagrams, I have misread the aforementioned.
There's no need for any form of apologies, although I may not possess the brains of David Lloyd George, or for that matter, the mathematical genius of Albert Einstein, I do appreciate you are trying to be helpful
