Interesting thread with food for thinking...
meanwhile, this is just Puerto Rico. You can see a huge variety of machete handles, but nothing like Guanabacoa. Or exactly Nimcha. But...there is even a Yataghan like hilt.

Could those handles travel from Cuba to Spanish Morocco and Philipines but not too nearer Puerto Rico?
If I make a search for Berber saber in google images most of what I get I think are old Dominican machetes (without guard). There is some kind of degenerated involution (see below) under the trademark Promedoca. The older designs possibly did not survive the artisan family that made them.
The so-called Berber sabers I unconsciously related to Espadas Anchas, but I was wrong here. They could be a naive attempt to resemble a dussack or a clamshell cutlass?
