Wrong hunting Gautrot XIX

Hunting horn brass of the Gautrot House circa 1880. A few bumps and dents, more dark spots (photos) beautiful decorative object (unless you are fan of hunting), in its own juice (copper is quite dull but it) is possible to Polish it to regain shine) 26.5 cm trunk diameter. I try to describe the particularities (negative or positive) of this object at best and in all honesty, however do not hesitate to contact me if you want any other details or photos I could omit; I am happy to respond as soon as possible.
