Thank you all for comment, very appreciated!

The rings which seems to be for a carrying belt I am as well never have seen before by a bhuj and also not this full tang construction. Soon as I will have it in my hands I will take pictures and will tell you the feel in the hands, I think that it's a substantial weapon and like Kai write worked for real business. If it's used on horseback I can't say, I just don't know enough about this sort of weapon.
Jens, interesting suggestion about the stylized elaphant head! Do you have an idea about the exact origin and an age guess?
Thank you again,
Detlef
