Today I received the tenegre and I am very satisfied with my new toy!
Handle is like supposed from horn, ferrule and guard from iron. The sheath missing two brass (?) bands at the leather throat otherwise it is in very good condition. The blade is very well worked and finished. The feel in the hand is very good and the blade is well balanced.
As for the age I think that it is pre WWII since the leather throat is attached in the old way. Here are some first pictures, more will follow.
