Kubur,
Congratulations, what a spectacular sword. It is indeed very similar to the one in Hales' book. The scabbard fittings and the hilt construction are like a takouba, while the blade is more like something one would expect to find on a nice, older kaskara. Therefore a Kanem Bornu or Wadai attribution seems reasonable.
It will be interesting to see kwiatek's translation as it may hold the key.
