Agree this is a Gayo keris with a Malay jawa demam hilt. Semi-sort of agree with Alan in that often kerises were changed, modified, upgraded, downgraded due to historical circumstances...however, unless those circumstances are known I don't feel there is any need to preserve the keris in its current state. It is not an historic or provenanced piece, nor is it particularly unusual. Were I the owner of this piece I would definitely seek an appropriate hilt and pendokok for the piece. An amalgamation is an amalgamation but an historically and culturally correct amalgamation is better than nothing
