Norman F. Brooks wrote an article on Cremonophones in the September-October, 1998 issue of the Canadian Antique Phonograph Society publication, Antique Phonograph News. He was kind enough to contribute much of the material on this page. The following scans are from the aforementioned APN issue:
Norman sends the following 1917 'launch' advert:
