The company was called Accordiana Melodiosa Excelsior s.p.a. 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. It seems that during World War II Sundqvist made Excelsior accordions under a license. At first Sundqvist imported Excelsior accordions from the United States, but later had his own accordion factory in Stockholm called Amerikanska Dragspelscentralen, the American Accordion Center. In the 1930s and 1940s Ragner “Raggie” Sundqvist sold accordions in Sweden under the name Raggie Special. At Magnante’s suggestion, Excelsior was made with wider piano keys than usual. Americans very often put the letter A on Excelsiors to reflect the word Archimedo. The rise of the brand continued after World War II. The Excelsior brand name quickly became known in the United States, and many professionals played with it, such as Charles Magnante, Art Van Damme, and Pietro Deiro Jr. The Bugari and Butti left Galizi at the same time. The Pancotti’s founded the Excelsior Manufacture Company in 1924 in New York. In the end, the Pancotti and Bugari brothers saved enough money to start their own accordion production. The Bugari brothers made the reeds, and Butti made the bellows. Because the Galizi’s did not know how accordions were made, they hired the Pancotti brothers to make the bodies and mechanisms of the accordions. They had set up a business only so they could make money laundering. The Galizi weren’t really accordion builders, they were smugglers. Upon arriving in the United States, they did not immediately have the possibility of making their own accordions, so they ended up making accordions with E. The Bugari’s were also cousins of the Pancotti’s. All of them had learned the art of accordion construction when they were young in Italy. When the Pancotti brothers came from Italy to the United States, New York, they were accompanied by two Bugari brothers who were reed makers. The factory was called the Excelsior Manufacturing Company. The Excelsior accordion factory was founded in 1924 by the Brothers Archimedo, Egisto, and Roberto Pancotti in New York.
