Nice example.  The yellow bands are gold washed silver.  Great to have the ivory intact.  I wonder if the later brass covering on the scabbard is hiding damage.  From what I can see the from the pictures, this could be Maguindanao. 
 
The blade needs a polish and an etch, and the scabbard needs some repairs.   
 
Congratulations on finding such a complete example with a scabbard!
