I do have a couple things like the NZ red covers and blue covers which used noticeably different colour tones .
Re Aust copies 9 and 10 - this may be a unintended colour variation. The yellow is not quite as yellow 11, but it's hugely different to the green colour.
Happy to put up pics but I don't know how.
