Nice kaskara. Likely imported blade. Any marks under langets? Being rigid it wasn't made of lorry spring steel widely used post-British conquest. Don't know how to assess cracks on top of crossguard.
The 1239/1824 date could commemorate the end of the Turko-Egyptian 1820-24 conquest of Sudan, though it may not actually be from that date, but why not? Blade looks too clean to be that old. See Wiki article re the first conquest.
