In the early 20th century the "Agati-Tronci" company, a known pipe organ manufacturer, began the production of cymbals, as they were difficult to import from Turkey. In 1926 a worker for the Tronci family, Fiorello Zanchi, left the company to start a new cymbal manufacturer with Manlio Biasei, the "Zanchi & Biasei" company. A number of cymbals manufacturers were founded in Pistoia after the First World War, starting a competition. On January 6, 1931 four companies (Marradi-Benti, Zanchi & Biasei, Rosati Leopoldo and A. & B. Fratelli Tronci) founded a cooperative society called UFIP to stop the competition between cymbals manufacturers. In 1947 Zanchi left UFIP to start his own company, Zanchi (later spelled "Zanki"). In 1968 UFIP changed from a cooperative society to an actual production company.
