maybe you've already seen this article.

or this model chronology

Yeah, those MAPA "Flight Test Reports" and the chronology are
excellent resources for hard-to-find information. I came across
them before posting. It's actually those documents that prompted
my questions - for example, I wouldn't have known about the
different rudders if the M20E and M20F reports didn't have graphic
insets showing them.
In fact, I have one more question to add to my original list.
The M20F report has another graphic inset that states, "N353JT had
the 'twisted' wing seen on '67 F and G models. It did nothing for
the airplane's stall characteristics and was dropped in '68."
I can interpret this to mean two different things. I suppose it
doesn't really matter, as none of the reports indicate one model
having significantly different stall characteristics than another,
but I like to sweat the small stuff.

For example, if I google
search for twisted-wing mooney, all I can find is a joke about
fueling them with a mason jar. I'm just left scratching my head
as to the differences between the wing styles.
