Hi Jose: 
 
Only way to know for sure is to take the hilt off and see if the gangya is separate. Right now I don't see any clear evidence of separation--the visible line is very straight and shows no edge corrosion or oxidation to suggest a point of separation that has been present for a hundred years or so. I've tried to take similar looking ones apart before, only to discover the gangya was not separate. 
 
If this is a hundred year old sword, it is in a remarkable state of preservation. 
 
Ian.
