From all the previous research that I have read, these swords are actually Dominican. One example is or was present in the Museo del Ejercito in Toledo, Spain, described as Dominican Republic, 1860 - 1864. Most seem to be from Cibao or Santo Domingo during the Dominican Restoration War Period or thereafter. I personally would take no mind to the sheath writing. It looks to be older but the description is more than likely by a previous seller that attributed it incorrectly. Here is the one that I have currently in my collection.
