from 1938 and 1939 give maximum take-off engine speed of 2850 rpm for both Merlin II and III
It also shows maximum boost at emergency power at 12,500ft as +10.55lbs at 3000 rpm for the Merlin III when you use boost override or pull the tit on 87 Octane.

Absolutely NOTHING to do with the use of 100 Octane fuel.
