This peculiar sabre was made around WW1 in Austria but destined for German use. It sports an early synthetic grip, not unlike the 1889 German cavalry sabre, but with a much more minimal knuckle guard. The grip is in good shape, except for wear damage on one side.
The montmorency type blade is in very good shape and the whole assemble is very solid. It is marked to Ed. Jung, Wien. Thank you to Dale Martin for the information.
