The pamor pattern of your blade is difficult to identify with some certainty because it is scattered and significantly worn-out. One assumption would be pamor tambal (patch) but I would rather think that it used to be a full pamor pattern such as lar gangsir (cricket wings) but eroded with time. Other opinions are welcome.
Regarding the style of hilt, I agree that it probably originates from Solo but am not sure that it can be classified as Narada Kandha because of its unusual curved shape, see a more typical specimen.
