N African, NE African or Arabian saber???

I am intrigued by the blade: it looks much nicer than regular Beduin stuff, with rather sophisticated fulled scheme and not very pronounced curve.
For all I know, it looks like a blade from Caucasian shashka.
A lot of Circassians emigrated to Turkey, Lebanon and what later became Palestine after the Russian conquest of the N. Caucasus. There still are Circassian villages in Israel and they are the elite force and personal King's guards in Jordan. The Beduins got their blades from all sources and a shashka would be a natural "donor".
Check the blade carefully for any markings.
