So as Mauro already knows I would agree on 18th century backsword with the second edge locally sharpened.
The blade marks were applied at the same time in my opinion and I would defer to Jim's overall opinion on them.
Turning to the hilt, the four petal design is in fact found on most brass hilted takouba, both Tuareg and Hausa. See attached.
For me the features like the "rain guards" make this a truly unusual example of a takouba and I would be proud to own it myself. Congratulations again to Mauro!
