Thanks Sajen, usually Minangkabau's hilt motif would not be of a Dragon but sometihing  like  horse shoe (tapak kuda). Agree with  you, maybe from Acheh.  If some of our Malay friends  could read the Jawi writing (Islamic script)  on the scabbard would be useful.It would solve the problem.  I could read only a little. The word Pedang (sword)  has been mentioned.
