For anyone curious the Merlin book is not as the title but more a technical history. From what I have read elsewhere some minor errors.
Two points of interest; at one stage trouble was experienced with failure of the magneto drives. Skew gears!
And for those who think they need electronic ignition, a sports coil, and .035 gaps for power, the Merlin has .012” gaps. (The energy to initiate other than a weak mixture is very little, and Seven owners are now almost as obsessed with power as were RR.)
