Tornado Throttle Quadrants

I first posted this over on Historic but it was suggested the knowledgeable guys on Modern Military might have more answers;

Are all Panavia Tornado throttle quadrants the same, or are there visual differences depending on the variant such as F.3 & GR.4 etc? If they are different how can you tell what model one is from?

It was suggested that the part numbers would be different per different variants, but does anyone know which number goes with which variant of Tornado?
Thanks in advance
