IMO not only the hilt is not appropriate but also the sarong with a notch on the back side in Palembang style? Yes, the blade looks nice with the patches of pamor tambal but I wonder whether this is an old piece as old panjang/ alang/ bahari blades have no visible pamor? Please also compare the fine greneng carving with the one on David's blade which is typical of such old blades.
