couple years old :^/ As I recall the acid had leaked
and pretty much
destroyed the boxes that were supposed to hold the batteries (I think
4 to a light).
This is a common problem with old (1930s) portable radios in the UK, many of
which used a wet cell LT (A) battery. The acid either leaked out, or
acidic vapour escaped and rotted the cabinet (and the wiring sometimes).
