Cavalry sabre with a parabolic blade

[fernando]

I have been chasing one of these for a couple years. Finaly i managed to convince this guy to trade the best (or less bad) of two examples he had.
Having (poorly ?) restored its grip with a new leather cover and wiring, he settled for a swap plus a few Euros.
Its blade curvature may not be the greatest out there, but is already within the not practical but exhibionist range. I wouldn't be surprised if the owner had this one for showing off in the streets and palace corridors and used a more 'reasonable' example for going into battle.
Judging by the stirrup hilt and all, this could be Portuguese, dated beg. XIX century, like from the Peninsular War period, i would risk; not an early example i know, but i had to have one of these bizarre blades in my in significant collection.
Any comments will be more than welcome.
