Good call Sergiu, it very well might be a shorter heavy type blade used for the hanger type weapons used by auxiliary forces such as sappers, miners and also by artillery gunners. The yataghan term is of course often misapplied in the description of some weapons, and of course used with reference to the bifurcated or eared pommel hilt rather than the weapon overall. I wish I had some of the reference books on Austro-Hungarian and Polish swords with me here in the bookmobile
I think some of the references might show this type of blade.
Its definitely a handsome sword in any case and maybe somebody out there might have more info.
All the best,
Jim
