Excellent Teodor!!!
The bottom sword is exactly what I was referring to! Although I have seen examples of these provenanced distinctly from Mexico, in a discussion with a distinguished author on Spanish Colonial weapons, he informed me that years ago these were identified as having come from Cuba during Spanish-American War.
I think it is important to remember how much maritime activity there was between the Maghreb, Cuba and the ports in Eastern Mexico as well as in Florida. These were all in the vast Spanish colonial sphere, so it becomes difficult to confine particular weapons to specific geographic area, except in cases where the volume of examples found would support the assessment.
Your observation on the hilt decoration similarity is well placed, and it is an important factor to focus on when investigating a weapon in this category. Since the blade is clearly a trade blade, and scabbards cannot be trusted in proper identification as they were often replaced or refurbished, the hilt is the best element for identifying the probable provenance of an ethnographic weapon.
I am with you in that I still feel reluctant to give up the possible Maghreb associations with these interesting sabres, and really do hope that others will come in with further discussion and more information. It would be great to see more examples of these also.
I am always curious about the purpose of the unusual profiling of the tip of these blades into what is termed a 'barbed point'. While these may eventually fall into a machete type denomination if the Latin American attribution becomes the likely source of these weapons, what practical purpose would such a point serve in actual use?
All the best,
Jim
