On the subject of #3, didn't they modify vintage mics for the 'Buddy
Holley Story', including some 55's? Seems I read, back when the movie
came out, a story about how they shot many of the musical performances live.
That doesn't mean that they actually used the mics that you saw in the
movie. There was probably an overhead boom mic that captured the sound
of the band, or maybe the singer had a hidden miniature mic to capture
his vocal. Good movie sound engineers are really good at placing and
hiding those things, and making a usable sound track from wild sound.
Or maybe they captured the band minus the vocal live and then
overdubbed that.
Movies are better than ever. 
IIRC, they did all of the above--including modding vintage mics with
modern (1978) elements--but that was 30 years ago. Possibly somebody
with a collection of EQ (or Mix?) magazines from the era could verify.
I believe that's where I read it....
