R-445 ORO-TONE Adapter To Play Any 78rpm Records on an Edison Diamond Disc Phonograph. This Oro-Tone No. 1-E Edison Attachment is used to play any 78 rpm style records on an Edison disc phonograph.

Included are its original box and information/instruction pamphlets. With a proper matching stylus (not included) the adapter head can be swiveled to play Pathe, Edison, and any Victor-style shellac record from that era (up to 1930+/-), but not any “modern” vinyl records.
