Hi David,
I'll bravely answer the call

This Takouba looks quite real, I don't see anything wrong with it that would make it a tourist piece. A central type piece I think...check out these great articles

and

Less embelished than the examples on the two sites, but still a good example. I think this one lost its brass ffittings on the hilt, and what is left is the bear rolled metal that makes up the hilt.
When I first saw your piece, the blade looked - and still does - curved. Is that the case? In the event it were curved, I wonder whether that would make it an Alguinjar instead of a Takouba.
About tha absent half-moons, my example is also lacking them:

All the best,
