Seeking Help with Excavated 1728 Pattern Bilbo Sword

The more intriguing is that Martinique, independently from its location in the Caribe, is and has been " so French as France itself ". Discovered by Christopher Columbus in 1502 Martinique, having become a French colony in 1632, never changed hands again, apart from a couple of brief English invasions in the early 19th century.
So, it doesn't make it any easy to assume that someone dug out a Spanish guard from the sands in French Martinique, specially considering that no combats with the Spaniards are registered to have taken place over there. Neither it is probable that the French imported trade blades, much less 1728 cavalry swords, from the Spanish.
But of course, all is possible.
