I'm waiting for Michael R. to explain that later production MkI*s were fitted with the MkII* seat back hardware.
It's probably not the case, that all the changes/ improvements were introduced at the same time. I would guess the introduction of the MkII* was more a collection of re-design features hitting the production line at one time, justifying the re designation to reduce the confusion in the parts supply and r&m instructions.
