I thing this is a good start: http://www.jshawmsc.f2s.com/merlin.htm

Not much different from late production Merlin III.

Note that the Merlin XX, which is also very similar to the XII (except of course supercharger, which is single gear in XII and two gear in XX) was cleared for +12 emergency boost (5 min, not altitude restriction) was cleared in November 1940.
