Unusual(at least for me) Valve stem

Finally riding a big boys bike
Hello, I just picked up a German, Rixe 20" girls bike and the rear tube has an unusual valve stem. It is not a presta or schrader style valve and I have no idea how to fill the tube.

Probably have a hard time finding Dunlop valve tubes in a bike store. Although they are still the standard in India. I've just drilled the rim out to Schrader size and used shrader tubes...
 
My Dutch bike came with Woods Dunlop valves on Continental tubes. Any decent bike shop should be willing to hit the catalogues and order you some tubes from Continental or Schwalbe.
