Spanish is one of my "mother languages", so in fact there's no real merit in me being able to fill the gaps... I'm used to antique inscriptions, also, especially in weaponry/cutlery, so this one was not that hard... it's people like Chris or Fernando who have real merit by being able to provide such huge amount of knowledge from the "outside", even if it's such a close "outside" as Portugal 
 
Glad to be of any help, always.
Best,
Marc
