Iraq 25 Dinars 1990, varieties

Hiya!
I have 3pcs of Iraqi 25 Dinars 1990. But all three are different from each other. I know there are three known varieties of this one, but it wouldn't suprise me if there are more, considering how slopy these are made. Maybe someone here could sort out what is what here, becaus I don't think they all fit these varieties.

In the description of the note gives the difference ..

But all three are different, but none of them are P-74c. Right? So are there more than three varieties?

In the SCWPM it notes that 1990 Emergency Gulf War Issue #74-76 Iraq printing. Many color shade varieties exist because of poor printing quality.
