I would guess that the final location was a cost saving & practical change. The area for the number is an extension of the water inlet boss & one machining operation did the water inlet & number boss. The earlier separate boss involved a separate operation & with the thoughts of mounting a generator in a few years it would need to be somewhere else in any case.
The final location would also be easier to stamp as the earlier area is cramped on one side by the timing gear housing.
