Co-inventor Louis Bacigalupi, Sr., is almost certainly the proprietor of
West Coast Organ Company of El Monte, Calif.  See Ed Gaida's article

The co-inventor named John Bacigalupi in the patent is quite likely
Louis' eldest son, Giovanni (John) Bacigalupo III, born 1895 in Berlin,
who later was proprietor of "Bacigalupo Söhne" of Berlin.
