Guys,
   
   I wrote to Albert Van Z to see whether he may have had more information. Here is his kind reply:

				Hello Ian, 
     
    The only (very concise) information I have about the 'Bankung' is, what is written on page 30 of 'Traditional Weapons ......', already quoted in your thread:  http://www.vikingsword.com/vb/showthread.php?t=20412 
     
    The drawing comes from 'Schröder, C.A., 1874,  Ethnographische atlas bevattende afbeeldingen .....' 
    The accessory text from 'Matthes, B.F., 1874, Boegineesch-Hollandsch woordenboek ......' only says: 
    "bangkoeng (hakmes)" 
    [hakmes (Dutch) means chopper] 
     
    That is all, I'm afraid.     
     
    Best wishes, 
    
    Albert

 From Albert's additional information, it seems 
bangkung describes a "chopper."  So I think the term is likely describing a heavy-bladed knife (with a belly?) designed for chopping.
