What's this?

Looks like a later version of the typically French "Nuit et Jour" machines, but is it original?
It would be interesting to see what lurks beneath the motor board, but collection only from Leeds prevents me from bidding.
For some unknown reason I cannot upload the WEBP images from the listing.

Very curious. I think this is unlikely to be as left the factory. You would need to look inside, as you say, to be sure. Perhaps a previous owner has added the radio horn attempting to improve volume or if done lately to improve saleability.

There doesn’t appear to be a way of shutting off the internal horn and directing the sound to the external one. If the external horn is just connected to the side of the internal horn I guess it produces little volume.

Looks suspicious, take a look at the lid stand, it seems to have been yanked out to let the lid travel 180 degrees and allow the horn to fit without crashing with the open lid. As Jamie mentioned, it looks like some homemade adaptation made on a Pathé portable.

A home cobbled contraption using a radio horn, presumably someone saw an EMG mk IX, from a distance
