FWIW, I have gear with mercury cells that are many years old
and still good. One problem is that they quit very suddenly.
I have used Alkaline cells in a Nikon-F using an O ring to
compensate for the smaller diameter and wound some foil on the
ring to create a side contact. They work OK and I checked the
calibration against the same meter with mercury cells, it didn't
change. The problem is that the alkaline cells have a short life
and tend to exude some sort of powder when the cells get old. You
can't leave them for very long periods. But, its fairly easy to
get old gear going again with cells you can get at the drugstore.
Basically hearing aid batteries.
A lot of mercury is used in fluorescent lights of various
sorts. There are recycling programs for them. Too bad the same
thing was not devised for mercury cells.
Note, that mercury cells and batteries were used for many
years as bias cells in electronic equipment. Difficult to
substitute anything in them but can be done. They had virtually
no demand so would last the shelf life of the cell, perhaps a
couple of decades.

do you know where I can buy such an adaptor to use LR44 (S76) Silver Oxide cells in Gossen?
