Not many parts to lose, just a ball bearing on a spring. The problem is
probably going to be burring on the edges of the detent slots, which can
be removed with a needle file. Putting the thing back together can be
unexpectedly tricky, though.
Firstly, you have to make sure you put the shutter speed ring back in
exactly the right position wrt to the little gear wheel which it drives
(otherwise shutter speed indication will be wrong). Secondly, beware of
the little widget that allows access to the red speeds - it's possible
to trap that so that you can't turn the ring at all.
