jambiya dagger

This is as far as i know a Jambiya Dagger with arabic inscriptions on it,It is silver and I think the handle is rhino horn.It comes complete with sheath which is real leather and the belt which has silver strands woven into it.My research show items that are alike however none are as complete as this. I am unsure if the exact date but it's been suggested that it is 19 century.There is some rust on the blade. This is handcrafted.

Thanks in advance for any help and advice on my item
