Brooklyn, NY. Founded by Evaristo Bona, Andrew Antoniazzi, and Dominick Brugnolotti, whose initials comprised the firm’s name. The firm serviced street pianos and fairground organs, circa 1912-1958. Converted many pinned cylinder organs to cardboard music or paper rolls; arranged and perforated both types of music. Took over the assets of G. Molinari & Sons in 1939.
