How could i be so blind that didn't figure out that those 'studs' are the hinges for a folding guard. To my defence, i was betrayed by the angle of the picture

. Actually, i have even discussed these features a few years ago over my (ex) pattern 1806 Portuguese Cavalry officers sword.
OTOH, for what i knew of Spadroons (Espadões) from a local fellow collector, i would never realize Kubur's sword is also one of the kind.
