thanks for linking to my page Sajen and I'm glad its helpful for you Darren.
This takouba looks to have a native blade and I recognize the decorative patterns on the hilt as well. The one side has a floral motif that is often seen on these.
This is probably a Hausa sword going by the decorative patterns on the leather. Although it doesn't have the large metal scabbard fittings sometimes seen on Hausa swords.
the scabbard overall resembles this one of mine pretty closely.
