I’ve been a “ Mustang nut” since I was a kid: more specifically, the Rolls Royce Merlin-engined P-51D/F-51D Mustang. None of the other variants particularly charmed me: the Allison-engined “A” and “B” models, nor, the Merlin-engined “C” model with a conventional early World War II P-40-like cockpit canopy. I’m not alone: there are zillions of Mustang nuts out there; I’ve talked to quite a few of them. I/we love the sound of the Merlin: the rumble/ roar/whine of it is like no other sound.
