   Try to test with ohm-meter ; but ways   
      
   According to description, it seems to be the old OA something (Ge   
   diodes), so 0.3V drop out and the diode-meter doesn't understand (it   
   never met such a component).   
   If you remove the black paint, you surely will see a cristal with a "s"   
   connected to.   
   Take care, after removal of the black paint, the semiconductor behaves   
   as photosensitive.   
      
   Can you post a pix ?
