Sudan arm dagger restore or not?

[Marc M.]

Greetings

I just bought a Sudanese arm dagger in a good condition exept for the handle,
and the arm loop is missing.
Top part is ivory and is missing a piece of the cilindrical part, the ivory piece at the top was broken in two pieces and was poorly glued and i glued the pieces again. Question: leave it as it is or restore it.I don't think the dagger is worth the restauration cost by a proffesional restorer, so probably a diy job. The ivory bird can be used for the missing part.
There is a text on the blade, a translation is always welcome.

Best regards
Marc
