Persian(?) blade and incongruent hilt

[Bob A]

I'd be slightly inclined toward India as the origin, based entirely on the vegetal ornamentation - Persian blades are often seen with animal representation. Steel scabbard also seems Indian to me.

I agree the hilt is a replacement. Huge blade! I'd figure a date range in the last century or two.

I have no basis for any of the above; uninformed opinion.
