Depends how they've been stored, I think. I understand that most cells that
depend on light stimulation of a metal like selenium or germanium will lose
their sensitivity with age. The generation of cameras with large selenium
cells would be in trouble by now if stored uncovered in a light place -
most would be 25-40 years old by now. I've been advised that the same thing
could happen to my lttle Leica CL which has a 'cell on a stick' behind the
lens (as does the M5) - they have to be replaced in as little as 10 years
depending on use and storage.
I'm not the expert on this - I'm relying on occasional comments in general
research - but older cameras with CDS meters seem to be more reliable (if
you can find batteries!)
