20th century Tuareg mounts, blade probably older. I have seen modern Tuaregs carrying similarly wrapped scabbards. Not sure of the function intended, except perhaps to save wear and tear on the leather...
Here's one example.

Nice enough sword, the leather and cloth looks pretty fresh so probably a tourist bring back since the 60s would be my guess. Also older scabbard rings tend to be round and brass. Can't tell from the photos if yours are brass or aluminium?
