Indian knife /specific name ?

[francantolin]

Hello dear members,
I got this nice knife with silver handle,
sadly without scabbard.
( scabbard must me marvelous if all silver worked)
It seems old, must be end of 19th century.

I think it come from India but I'm not 100% sure,
Could you hello me to fix it .

Last: I wonder if an etching could reveal a pattern?...
