Unusual nimcha blade: need help

[ariel]

Here is a run-of-the-mill Moroccan Nimcha.
One unusual thing about it is its blade.
As a rule, Nimchas carry curved saber blade, and the majority I have encountered thus far are European trade examples.
This one has straight blade with large false edge. Also, locally-made blades have 3 narrow fullers. This one has 7.
The fullering and the false edge ( and, to a much less degree, straight construction) are very different from the usual local pattern. No markings to claim European origin.

Is this a more sophisticated local production?
Or, trade European blade with no markings?
