You're quite right, I was confusing the "Wein Cell" for the adaptor you mention. Although I gave up on Olympus years ago, I'd be interested to hear if the above use of silver oxides with converter is satisfactory? (i.e. accurate)
since other older cameras that previously used the mercury cells also need this conversion
