Thank you so much, Gentlemen.
I knew i could count on you

.
Jim, your comprehensive input is always precious; i am much obliged for that.
Thanks a lot for having resourced Ottmar, Michl ... and what a surprise. Why Portuguese ? I have read of Slavonic soldiers using Schiavonas when fighting in Spain, but Portugal ?
Jasper, your remarks and enlightening pictures are, as always, of the best, and i thank you so much for that.
Well, i confess that, digesting the quoted provenance of this example as been Portuguese, is something that will keep me awake tonight

.
If any of you Gentlemen wish to extend his opinion on such issue, i will gladly welcome it with great pleasure.
Just a note to report that, i find it interesting that this blade slightly widens in its last section. I wasn't expecting this feature in these swords or, at least, in this particular one.
Any ideas?
