The Talking Machine Forum — For All Antique Phonographs & Recordings

Hi All,
In looking in the forum one item recently grabbed my attention the Oro Tone adapter for the Edison DD. I am interested in how popular they were or how common they are today.
Thank you kindly,
Allen

Advertised and marketed with much effort and for many years. So, not rare.

The Oro Tone was not the only adaptor for Edison Disc players to allow it to play standard records. There were many brands.
