=>BTW, if anybody is going to try and convince me that there is a 'correct' =>'OO' height for mounting US style knuckle couplers on a 4MT, then be advised =>that you're wasting your breath ;-) =>

Well, Steve, as long as that kind of attitude prevails (and for some reason I can't fathom it seems to be the prevailing attitude among "serious": modelers in the UK), there is really no incentive for any mfr to adhere to an kind of standards - not even their own.
It's not a matter of a "correct" height, it's matter of a _standard_ height, so that products from different sources using the same coupler will couple reliably with each other. It should also be obvious that a common mounting method is essential, so that changing couplers doesn't entail modfications to the frame, etc. It doesn't matter squat what the standard is, so long as people agree to use it.
I have a part-English background, spent many of my childhood years in Stratford-on-Avon (when it was still LMS and GWR, and later when it was BR), and dabble in British outline modelling. But the lack of standards with regard to wheels, track, buffer beam height, etc etc etc is just too much. When you have to fiddle with just about every piece of rolling stock to make it match and work reliably with what you've already got, something is seriously wrong.
