As a P-3 guy who had to learn the 'revised' emergency procedures based on AF586
The C-130E/H uses nearly the same engines, gearbox, & prop, although I gather from the book, that the cockpit controls differ between the two airplanes and there was also mention of the oil supply valve circuit breaker and its relation to the emergency fire handle. Speaking from the AF side, the procedures and even some of the wiring has likely changed in the Herk fleet from then to now anyway.
While I understood 99% of the systems aspect of what happened to this P-3 and the criticality of the "prop fails to feather" checklist, I admit I didn't get the internal failure in the prop dome completely. The fact that the prop oversped to such a ridiculous RPM without achieving an earlier pitchlock took me by surprise. Also, the findings at the end of the book which claimed that gearbox failure was a likely eventual outcome regardless of the success of the "fails to feather" checklist was another surprise. I'll likely read up on this in the coming weeks.
