Was this perhaps an equivalent of G-14, ie. same as G-6 but with all the goodies put in? Was there a similiar tendency for standardization of the most up to date parts, apart from the US manufactured Merlin?
IIRC the main reason for the different mark number was that the Packard built merlins needed different parts and tools to the Rolls Royce merlins. The different mark ensured that MkXVI equipped uints got the right supplies.
I assume that the MkXVI incorporated whatever was standard on MkIXs at the time of their design. In general RAF aircraft seem to have been fairly standard and changes propagated pretty quickly from one production centre to another.
