If you go by Eric Claude's book on Moroccan and Algerian arms, he seems to use Genoui for shorter daggers, and Sboula for the longer ones. Yours would fall into the Sboula category based on size. Not sure if such classification would be correct from a traditional point of view, as is the case with a lot of terminology that is frankly the invention of modern collectors like us.
It is Moroccan, and I would date it to the late 19th, early 20th century. I cannot tell from the pictures, but is it possible it was made from the blade of an M1874 Gras rifle?
Very nice item, good acquisition.
