I agree with Mr. Detlef, it sure looks like a sunda pedang. 
 
But there appears to be no missing piece of wood. It just has a metal frame to exactly protect  the wooden ferrule from chipping. These metal frames came about during the 19th to mid 20th century. Seems to be an afterthought after a lot of old wooden handles started to get broken inadvertently during handling. 
 
Just my humble opinion
