I'm not sure if the tonearm is from an Operaphone. (Wasn't the tapering gooseneck tonearm exclusively produced by Victor in the US prior to 1925, and others barred from manufacturing their own versions due to patent restrictions?)estott wrote:Do you still have the Operaphone? Here's an Operaphone tone arm and reproducer on Ebay!

It may have been installed on the machine by a previous owner to replace one that had crumbled away. I know when I bought my circa 1920 Silvertone years ago, it had a Silvertone sound box attached to a conventional Victor tone arm. After I replaced that with an authentic Silvertone tonearm, I noted quite a difference in sound quality--the tapered Victor tonearm was much better.
