Brake Pad Supersessions

Over the last twenty years Land Rover have kept changing the part numbers on brake pads. 

One reason was the change from asbestos based pads to non-asbestos, but this does not explain all the changes. 
We have been asked to provide a list of these changes or supersessions by a trade customer who tries to keep a good selection of pads in stock. He has found the mass of part numbers very confusing and wanted this list to make sense of it all.
So having done the list we thought our trade customer might not be the only one to find these part numbers confusing. Consequently here is the list for anybody else who might find it of use.
