In regards to the age, based on the simplicity of the hilt design alone I would guess that it's from the 18th century. Based on the very odd (almost completely idiosyncratic) short and stubby pommel spike, however, I would give it a later date, like being from the 17th or even 16th century (this given that khanda/firangi hilts with atypical pommel spike designs seem to be more common in earlier periods than later ones).
Are there any decorations/carvings remaining on the hilt? Older hilts (at least in south/central India - where this sword is likely from) tend to have more designs engraved/carved/chiseled into them, where as later ones were more simplistic in nature.
Overall though I would say it's likely 17th century.
