Sorry it has taken me so long to post a reply about your very nice new addition to your collection, but I was trying to locate a photo of the hilt of one of my daggers to add for comparison to your sword/long dagger. As you can see the carving on the two hilts is very similar in their detailing. I am in total agreement with what has been said so far about your piece so I cannot really add anything new to the discussion. Again, my congratulations to you for your great luck in finding this.
Best,
Robert
P.S.
I want to mention that the horn hilt on my dagger is actually as dark as your example and that the only reason it looks this light is because of the lighting used to try to bring out the detailing when the photo was taken.
