Although maybe the input could of been for a wire recorder which wire recorders were around at that time.

Oddly, it appears that the earliest phono cartridges were magnetic...from Wikipedia:

“The first commercially successful type of electrical phonograph pickup was introduced in 1925. Although electromagnetic, its resemblance to later magnetic cartridges is remote: it contained a bulky horseshoe magnet and employed the same imprecisely mass-produced single-use steel needles which had been standard since the first crude disc record players appeared in the 1890s. 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type of magnetic pickup completely dominated the market well into the 1930s, but by the end of that decade it had been superseded by a comparatively lightweight piezoelectric crystal pickup type.”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. https://m.youtube.com/watch?v=87P7xygDcs0. I own a R7 tombstone and that changer mech (mine needs a cartridge though) I have plans once I find a cart to build a wood base for the changer mech and wire it to my R7.
