It was this material:
http://www.coe.ufrj.br/~acmq/tesla/oldtesla.html
The devices were used for electroterapeutic treatments.
By the way, the diathermy machine has a tesla coil with a flat

The handle at the top allows to vary the coupling between the primary 
and secondary coils by moving one of them sideways.
I restored the big static machine and some induction coils.
