On the Origins of the so-called Berber Sabres

[TVV]

Here are some more pictures of the sword, which I have been lucky enough to acquire. These swords are on the shorter side, and this particular one is quite light as well, especially compared to my other mystery/berber sabre.
Now, onto the identification.
The blade most certainly has NO ME SAQUES SIN RAZON - worn off a bit, but still there. Interestingly, the second part of the popular Spanish motto is missing - it is not on the other side of the blade, just nowhere to be found.
The cloth baldric has faded, so I doubt anyone would be able to use it to point to the sword's origin.
The scabbard is of a peculiar construction - instead of two symmetric wooden halves, it has just one, from the decorated side. The side, which would press against the body has been left undecorated. Does anyone recognize the scabbard decoration?
Finally, it is a full tang construction, kind of like a machete. There is file work on the spine of the tang, which reminds me of something - I think of the brass spacers on the hilt of an Albacete dagger?
Hopefully, the pictures will help someone to come up with an idea based on the various elements and their decoration. Given how I now have two of these sabres with Spanish mottos, have I inadvertently crossed into Spanish colonial weapons?
Best regards,
