I suspect this item is a recently made fantasy piece. The graphics are unknown and don’t correspond to anything I’ve seen on unquestionably genuine German horns. Look at the only photo the seller provided of the horn’s interior. Although the bottom rim is splotchy, the interior is pristine and is constructed differently than any unquestionably genuine German horn I’ve seen. This reeks of a recently made fantasy item.
