Swedish magneto telephone, schematics missing.

[dsk]

This one has been in my basement for years, it has a story as used on The raceway in Karlskoga. Sweden.

I do not have any documentation, but I know it has been used as late as in the 70'ies.

If someone may help I could learn more  .  Ill guess this are one those who never will come up on my walls, but it is interesting to know about it.
