'Transmitters' circa March 1920?  I just had a quick peek at Rust's
American record label book, and he mentions the (experimental?)
electric recording of the burial of the Unknown Warrior at Westminster
Abbey on 11th November 1920 which had been pressed by Columbia, but he
gave no further information regarding it.
