Thank you for your answers.
I give the dimensions of the sabre:
overall length: 950 mm,
blade dimensions: length. 815 mm, width 32.3 mm, ( at the hilt 41.3 mm), thickness 6.2 mm...,
deflection 2 cm.
The blade has a length like that of a cavalryman.
The head is springy. When held by the hilt (tip) it bends like a spade.
The sabre scabbard is made in a primitive manner. Two woods connected by nails. The wood is stained. At the ends of the scabbard were applied clamps of brass plate.
