During World War II, the company performed defense work, as did most all instrument manufacturers.
Following the war, Elliot Kehl secured a controlling interest in the company and began development of several new products including the Farkas Model French horn and a new line of saxophones.
It only diversified into instrument manufacture about a century later.
Hawkes & Son was originally founded in the 1860s by William Hawkes as an importer of muscial instruments, later venturing into music publishing and instrument manufacture.
Bach aficionados will generally keen to point out that most Bachs are good instruments, however.
Unable to make the rent at times, Holton was known to pawn instruments at a shop on Clark Street between 18.
It would be home to Frank Holton & Company for only a decade.
Hence, I don't think there were any trombones produced at the previous site (I haven't seen any evidence to suggest the opposite), but don't quote me on this!
In 1953, Bach moved factories again, this time to Mount Vernon, New York where production continued until the early 1960s.
In April 1918, Holton opened a factory in Elkhorn, Wisconsin moving over 200 employees and 85 carloads of machinery from Chicago.
