Another example with interesting inscriptions in Spanish ended on eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll...K%3AMEWAX%3AIT
On one side the inscription is "Para Los Valientes ____enos", as opposed to "Para Los Valientes Dominicanos" on one of mine. On the other is what looks like a regimental marking - can someone read and decipher it? If this sword can be ascribed to a military unit, then that would likely provide a conclusive answer on who used these interesting swords. In any case, the Berber attribution seems more and more unlikely.
I am attaching some pictures from the auction.
