This lovely fittings looks Malay, to me.
The blade had been repaired. The 'belalai gajah' (or kembang kacang, the curled area at the base of the blade) seems like an add-on work, the weld lines does not flow towards the curl. The flow of the 'luks' (waves), seems 'disturbed'. Number of luks...hmmm... 10 or 11 (?).

Overall, an authentic old piece.
