... And after writing this I realised that I had not considered flipping 
the bars around... If I swap the back bar of row 8 with the front bar of 
row 9 and flip them the other way around they seem to match properly... 
I still have no idea if this is correct... I wonder if any other pairs 
are swapped around.... any other advice or information on what order the 
codebars need to be in my version of they keyboard would still be helpful.

Cheers,
Troy
