Jasper, that is an amazing hanger! Beautiful silver work and I love the face on the pommel cap! I see it was made by the Wundes family. The length of it perhaps indicates it wasn't just a hunting implement, but a weapon as well. The grotesque monsters and faces were popular on English and Dutch swords of this period. Since it is something different for you, feel free to let me reduce your stress and take it off your hands for you!!
