In 1918-1919, H.A. Bemister advertised U.S.-made phonograph needles from the Mappin & Webb Building, 10 Victoria Street, Montreal, Quebec, as did Arthur K. Kempton from the same building. By late 1919, Bemister promoted a wide range of phonograph accessories and supplies.

In November-December 1921, Bemister advertised in newspapers across Canada the Phonograph Record Repeater, "the marvelous Canadian invention that re-plays records as often as desired" from The Phonograph Record Repeater Company, 122 St. Antoine Street, Montreal, Quebec.
