Thank you all for your excellent replies. It seems that the origin of these sabres will be subject to a fascinating discussion until we are able to find a contemporary photo of a warrior wearing one. I can deffinitely see some justification in a Central American attribution - the blades, the motto on mine (most certainly not etched in the Maghreb), and the guardless hilts with horn scales not dissimilar to some Mexican swords and knives. While I will be quite happy with whatever it turns out to be, for the discussion's sake I am going to argue in favor of a Maghreb origin.
Searching the forum, I was able to find a shula, posted by ErnestoJuan, with hilt decoration quite similar to the decoration on the hilt of my example - note the little crosses. Here is also a close up of the hilt of a sword sold by Oriental Arms, and its inlay to me looks similar to the inlay found on the hilts of certain daggers from Mauritania. Although the Latin initials certainly complicate this theory.
Finally, I have attached a photo of a sword, Artzi had identified as originating from Spanish Morocco. Jim, is this what you were referring to as most likely coming from Cuba?

Teodor
