This dagger is in outstanding condition considering it is almost 200 years old. It's the only one I've ever encountered. When the Austrian chapter was done in my Volume II I was unable to come up with a photo of this model and had to go with a drawing. The grip is a replacement although I don't know when it was done. This is reflected in the price which is $1,600. If it had the original grip it would be at least $2,500.
