Thank you so much Gentlemen, for your comprehensive comments and the treatises on these swords. 
I will be digesting and saving to my archives, all those precious details. 
And once Keith notes that there aren't many of these swords out there, i will here upload a high end example, that comes in AS ARMAS E OS BARÕES, by Eduardo Nobre. The silver hilt has gilded decorations, and zoomorphic figures.
