True meter failure (as is seen so often on 2s's) is characterized by the
meter not reacting to light, but the indicator is always near the lower
end unless extreme inputs are made -- coupling ring pegged, or ISO set
very high, etc.  And everything else works just fine, even auto and
manual exposures -- it's just the display that's farky.  Sounds like
you've got a number of issues, some of which may be circuit-related, but
there's a good chance most are mechanical.  In other words, there may be
hope.

The slipping pin on the rewind lever has several solutions.  For a long
time we just cut a longer pin from a paper clip -- I've still got paper
clips all over the place with one leg cut short!  But the last few years
we found that you could just put a slight bend in the pin, so that it
didn't slip sideways anymore.  Either way is fine, I suppose.
