This is also a Peninsular piece which in Kelantan is usually called a "badik Bugis" ie. Bugis style, to distinguish it from the more typical Malay badik which have the mar.   
 
BTW the piece pictured in post #5 is a typical Kelantan style badik and looks like a nice one.  Good ones are hard to find.  If you have the scabbard I'd love to see it. 
 
Also, the piece in post #3 now belongs to me.  Such double edged blades are almost certainly a European influence adopted from Western military style blades.
