Peacock car horn early 20th

Very beautiful car horn or carriage of the brand peacock (stamp on the beak) which dates from the beginning of the 20th century. It is made of patinated gilded metal, copper it seems to me, or brass perhaps. It will be of the most beautiful effect as an original decorative object or will delight a collector or restorer of old cars. It has a nice patina and still works (when you manage to blow in it) but it lacks its pear. It is in its juice with multiple marks of its age: traces of whitish corrosion, marks of blows, stains, deformations, scratches. Its diameter is around 22 - 25 cm depending on where you measure, the diameter of the opening is 8cm. It weighs about 200 g.
