Unusual Lance / short spear

[B.I]

this is indian and northern, probably rajesthan. i would think it dates to early 19thC and i think the whole piece is original and en suite. its a good thing and you did well to find it.
the decoration hints at a kutch style, although somewhat cruder.
the makara clamping the blade is a southern trait, although also used in the north, as in this piece.
well done!
