Although my first thought's were along the same lines as Jonathan's, there is perhaps one other small possibility.
I've seen processional/festival pieces with a-typical brass hilts.
In fact I know of a sousson pata with a much simpler brass hilt with small 'cymbal' type noise-makers built into it so that presumably it will make a 'clang clang clang' noise as it's carried if it's jiggled up and down and I've held that sword and the blade is fully 'live'.
I've seen pictures of them carried at the head of processions at festivals.
Beyond that possiblity I have to agree with my esteemed collegue Jonathan's assessment of age at around 1900-1930 and that it 'feels' more 'form' than 'function'.
The casting quality of the hilt would also fit with that: 'new' enough to not be of the finest 'antique' quality, old enough to still be quite good.
The Indian's have been making pieces to appeal to foreigners interested in thier rich culture and traditions for...... well, as long as anyone!
Either way, I think it's an attractive piece with genuine age.
Edit: I'm not saying this is a sousson pata of course because it's not.
