Its tracking weight was specified in ounces, not grams. This early type of magnetic pickup completely dominated the market well into the 1930s, but by the end of that decade it had been superseded by a comparatively lightweight piezoelectric crystal pickup type.”

I totally missed this. Yes the RCA R7 which others have said this set was a rebadged version of was sold both as a tombstone and as a radio Phono console with this changer with a magnetic cartridge.
