FIAMM CTO MERCURY 12V fanfare horns

Vintage FIAMM CTO MERCURY fanfare chrome horns in used condition. They are complete, look untouched and I did not test them. One horn has a bigger dent (see pic #2 left horn). Apart of the dent all is ok. The chrome is not too bad and possible ok after you polish it. One horn is for high tone and one for low tone sound. The diameter is 9,5 cm and the length is 14 cm. The badges are stamped with “FIAMM CTO MERCURY 12V” and the rear is stamped with "A FIAMM" "B FIAMM" and "Made in Italy, MODELLO DEPOSITATO". The last picture shows the fanfare horns in an 1960 German Auto-Parts Catalog. The catalog is not included.
