There's a solution to the mercury battery issue.  My 35 year-old Canon
35mm SLR camera  requires PX625 mercury cells.  Today, since they're
illegal in the US from what I understand, there exists what's called
the 'Wein cell'.  1.35V zinc-air battery.

Of course I don't know exactly what the PC-1211 requires, but it's a thought.
