Remnants of a medieval scabbard (probably 14th century)
This scabbard is currently at display at the Rothenburger Reichsstadtmuseum, where I took this photo. I unfortunately don’t know it’s origin and age for sure, but I guess the shown plaque maybe associated with it, so it would be from the 14th century. You can see it’s inner setup: thin wooden core, several, broad risers made with loops of string and a thin leather covering, which lacks any tooling. The scabbards mouth is covered in very ornate silver metalwork.
