In order to keep the quality of the accordions high and to meet demand, the new Excelsior factory was founded in Castelfidardo, Italy, in 1946. The company was called Accordiana Melodiosa Excelsior s.p.a. The company was founded by Egisto Pancotti, who had moved back to Italy. These instruments often display the letter E, which refers to Egisto. This company was in operation until 1984.
