Here are now larger pics from Bigroby.
Value is something personal. Do a look at the big dealers sites in the net and detract about 20-30% and you have an idea of it�s current worth.
Although the dagger is in a throughout nice and collectible condition the crack in the grip, the not too clean blade and the dents in the scabbard might cause additional discounts.
The dagger has the socalled 39-41 trademark of the EICKHORN firm at Solingen, but the crossguard eagle and the kind of grip variation is commonly attributed to the earlier period (such parts have been used also in later periods).
